I read project readme, checked client side and server side configurations, and no such feature exists - YES
Although you said that mods trying to change player model modification will never be compatible, I still want this feature.

Is your feature request related to a problem? Please describe.
I'm always frustrated when using Yes Steve Model and First-person Model。

Describe the solution you'd like
I want the attack animation to work properly when I use the Yes Steve Model and the First-person Model.

Describe alternatives you've considered
I tried searching for similar mods online, but couldn't find any results that could solve this problem.

Additional context

I have zero room for action here.
Yes Steve Model needs to add support with PlayerAnimator library, or implement its changes in a more compatible manner.
