sinytra connector is doing good right now, but fixes can be made like making proper integration with fabridge mod you can improve it to fix certain connector bugs and errors with incompatibilities with fabric mods, and now an extra library could be made as translator, which would translate the code of the fabric mods to the forge architecture and then recompile it via a server if it isn't compatible via connector itself

edit: also recommended to make a forge version of the quilted fabric api for good compatibility with quilt on forge: https://modrinth.com/mod/qsl and could be used as a library for adding quilt and fabric tools to forge
