You can't set a default block to be placed in when logging in or leaving a non-block space, right? That would mean players who dislike... what would you call them, NSFW blocks? would potentially be placed in one when they wouldn't want to be.
There is already a priority option toggle for beginners blocks in the game's settings, adding another one for "(un)censored blocks only" is a trivial task (it would have been even if the former wasn't there).
If you think that's bad, remember that Universe had some attacks' distance tied to frame rate.
I used to play FPS competitively (many) years ago and frame rate affecting one or more aspects was the norm in that kind of games.
I don't think that it was bad, nor that it is bad that height affects the hitbox size.
