We have people thinking they should expect ruler flat response and supposedly "perfect" results. Not gonna happen in probably 95+% of rooms. Of course, you can simply cut out a ton of low end! Problem fixed. Except for the fact it's not as convincing a reproduction of the real music experience. :( Who needs LF? The music lives in the midrange, right? Ugh. Like putting a speed governor on a race car.
Someone will mention subs with a smaller speaker, but you are still stuck then with the compromised mains.
You also bring up a good point in regard to driver integration. Everyone is different in how accepting of less coherence they are. Having used coaxial and full range speaker drivers I can appreciate that caveat.
