Based on a quick lookover of bug reports and this thread, there are issues that the height 'restrictions' have introduced, and the fact that it seems to negatively impact more people than positively impact.
Short people exist, tall people exist, they are even shown in the gameplay, so any immersion breaking from a player being the same is moot.
I don't see a viable reason to keep off-brand changes for the sake of 'someone's bad imagination.'
Salon shops are breaking for Casts (noted when aux's are made as well), some people want to just cosplay/emulate characters, etc, and all of this because... no given reason.
The only defense to keep it so far?
Short people in G-strings plaguing their gameplay? That the providing person couldn't even find an example of from the original, supposedly plaguing a majority of parties, and instead provided a pointless visual bug?
Heck, one of my favorite voice actors is 4'9", and the other playing a certain creepy cast barely makes the cut, assuming outfits don't break and suddenly things can't be worn due to 'the game never being designed to limit/cap height'
This has no direct impact on me as I made a 'taller' JP character who honestly might be 'too tall' if the upper limits are true.
Instead of trying to curate all the item combinations that will break in the salon, just remove the limitations and worry about individual items that may be 'culturally off-putting' although personally, I'm already worried about what little is going to make it from collaboration events.
PC opening up shortly is going to make this far more available, and as such, the cheap limiter far more apparent.
