Sticking to Frabric may not be wise.
Yea you got the support of large youtubers who use it regularly.
But if you don't head to forge... they may drop you, because other mod makers stick to forge, specially with how Fabric isn't the same as forge and requires extra work to even use mods.
I hope you switch this to work on both. I mean you did normally work on Forge up to 1.12.2
