Meet the new forge, same as the old forge. Forge has been forked, with the majority of forge’s developers moving over to the fork, NeoForge. They hope to implement some major improvements come 1.21 and maintain compatibility with Forge mods on 1.20.
This is the part where it made it doubt. Sounds like they are supporting 1.20 Forge mods only.
Quilt is based on Fabric. While currently supporting Fabric mods, at the start they were actually not planning on keeping this compatibility. I don’t know now.
There are a couple of Quilt modpacks, but most mods in them are for Fabric still. I don’t think there are too many mods for Quilt yet.
