The FMLModType manifest entry is included in fabric jars which causes issues with things like Sinytra Connector.

In addition FMLModType is LIBRARY when in modern versions it should be GAMELIBRARY as LIBRARY is meant for plugin layers while GAMELIBRARY is meant for mods/code that references minecraft code in the game layer
