Help me understand "the swarm" in the broader audiophile world

I'm still fairly new out here and am curious about this Swarm thing. I've never owned a subwoofer but I find reading about them--placement, room treatments, nodes, the crawl, etc--fascinating. I'm interested in the concept of the Swarm and the DEBRA systems, and I have a very specific question. The few times I've been in high-end, audiophile stores and asked about the concept of the Swarm, I've tended to get some eye-rolling. They're selling single or paired subwoofers that individually often cost more and sometimes much more than a quartet of inexpensive, modest subs. The same thing can be said for many speaker companies that make both speakers and subs; it's not like I see Vandersteen embracing the use of four Sub 3's. 

My question is this: do in fact high-end stores embrace the concept of multiple, inexpensive subs? If not, cynicism aside, why not? Or why doesn't Vandersteen or JL or REL and so on design their own swarm? For those out here who love multiple subs, is it a niche thing? Is it a certain kind of sound that is appealing to certain ears? The true believers proselytize with such zeal that I find it intriguing and even convincing, and yet it's obviously a minority of listeners who do it, even those who have dedicated listening rooms. (I'm talking about the concept of four+ subs, mixed and matched, etc. I know plenty of folks who embrace two subs. And I may be wrong about all my assumptions here--really.)

Now, one favor, respectfully: I understand the concept and don't need to be convinced of why it's great. That's all over literally every post on this forum that mentions the word "sub." I'm really interested in why, as far as I can tell, stores and speaker companies (and maybe most audiophile review sites?) mostly don't go for it--and why, for that matter, many audiophiles don't either (putting aside the obvious reason of room limits). Other than room limitations, why would anyone buy a single JL or REL or Vandy sub when you could spend less and get ... the swarm?

as a dealer with 30+ Years experience i love to talk about the application  of real world solutions

A swarm would sound better than one or two subs most people do nothave the room or desire to have 4 subwoofer boxes in the room along with a pair of main loud speakers
So the reality is swarms almost never come up based on practicality vs performance

In fact we are now importing a line of suberb subwoofers from the uk that are better than Rel and are the ideal partner for a monitor as the subwoofers that are tall enough to allow a high end monitor to sit on top of the wooofers   https://mjacoustics.co.uk/kensington

Many of the issues addressed by multi-subwoofer setups are also addressed by dipole bass designs.  Dipole systems may not go as deep, but they can be more accurate.

Many systems have a relatively small “sweet spot”. Adding a swarm might distribute the bass across the room better but the rest is largely directional and best heard in that sweet spot. You only need one sub to get the bass filled very well typically in a single listening  spot.  

Audio Kinesis (Duke) is also very knowledgeable and big on sound dispersion in general and I believe tries to enlarge that sweet spot with his designs. When that is the case ( a larger sweet listening area) the case for a more evenly distributed bass is also better.

Someone mentioned dipole speakers being less susceptible to bass nodes. I use Ohm Walsh speakers which are pseudo-omnidirectional (very wide but controlled dispersion with all but the highest frequencies) with a vertically mounted bass driver and that approach too seems to do well in of itself so speaker design is also a factor for how well bass gets distributed.

A dipole bass is great but only if the backside is in phase with the front.

Hmm well another advantage of the Ohms is it’s coherent design using the proprietary CLS (coherent line source) Walsh-style driver.
