The top tier of talent is still OK, aside from 135/145, but that's like 10 total fighters at 115/125. So yeah, it's bad, but it's always been bad.
I have no idea what the development pipeline for WMMA looks like. Are there more women getting into MMA when they are like 16-20? Are there more women in related combat sports than before (wrestling, BJJ)? What's the scene in Europe/China/Mexico/Brazil? I honestly have no clue.
It seems like you have some that probably start training as they were fans or their boyfriends train, people that did MMA/kickboxing for exercise and kept going with it, then some tiny percentage of women who were in related combat sports, which are themselves super niche sports.
Then on top of that you need them to want to get brain damage and be great athletes (Joanna, Cyborg, Holm, Rhonda, Rose, Kayla etc. are good athletes.
If Dagestan let girls wrestle it might improve things, but I don't think they are allowed outdoors in broad daylight.
