Seeking Terraform Open Source Backend Maintainers

I only just saw this now, noticing that the manta remote storage backend got deprecated in terraform v1.2.3 and removed in v1.3. I guess it’s too late now to get it back into the code base, if I’d offer maintaining it? I read something about a planned plugin system for remote state backends, would this be the way forward then? I guess I’d have to stick with terraform v1.2.x for now then?
