The problem is that it's not about human language. If it was about human language, the consortium would give a shit about Bengali speakers. It's about the sensibilities of a small, particular group of privileged people, in a particular time at a particular place, who consider their weird priorities to be universal.

Let's not forget that adding all this complexity to Unicode has a real burden for people who implement Unicode. In practice, the consortium has to prioritize what symbols to support. So, in practice, it's less "embracing all variants of human expression", and more "the ability to communicate in your native language doesn't matter as much as the gender identity of this police emoji".
