With my former passive configured all-horn speakers I at one point had 3 processing stages involved: the passive cross-overs in the speakers as an analogue "processing" stage, the Xilica DSP to high-pass them, and JRiver Convolution hosting a software for room correction in both the amplitude and time domain. It was a capable setup overall, but I prefer my current fully active setup with only one processing stage: the Xilica DSP. Room acoustics have been optimized with both diffusion and light absorption, so no room correction.

interesting, i actually own a "new-in-box" un-openned Xilica DSP XP-2040 i had purchased to use with my Trinnov for my 3 subwoofers (happy to sell it cheap). it turned out that my 3 Funk Audio 18.0 subs in my Home Theater have an even better internal crossover, the ALLDSP module that is able to be ethernet networked and tuned remotely.
but back to the subject of a dsp crossover and whether it’s suitable for the top level 2 channel music reproduction?
i think we see it mostly in high performance 2-channel with DIY active horn systems where otherwise it’s just not very doable. so in those situations it’s simply the only choice, not that it’s inherently better than analog.
for instance Magico brought out their $600k Ultimate Horn System some years ago, but it used a dsp crossover for the best performance and they only sold a few. the marketplace did not warm to the dsp idea as most high level users want all analog signal paths. we can argue about performance, but 2 channel at the top has it's perspectives.
it is interesting that the new G3 version Avant Garde Trio uses a completely analog crossover.
