So I noticed that Enhanced Block Entities did some changes in model bakery(https://github.com/FoundationGames/EnhancedBlockEntities/blob/1.19/src/main/java/foundationgames/enhancedblockentities/client/model/DynamicBakedModel.java).
However, unlike #107 , in 1.19.2 fabric, they somehow work together without visual glitches.
I was wondering if using them together results in even better performance?

I believe the "DynamicBakedModel" EBE uses is only for its own purposes of replacing the chest, etc. renderers, and does not apply to other models.

As long as it works, yes, because ModernFix currently makes no optimizations to chests by itself.
