This is my last try--I've tried PMs at the Minecraft Forums and CurseForge.

Zot, are you still modding? If so, are you planning on porting OnlySilver to 1.15.2?

If not, I plan to port it, as it is needed for Sterling & Black. If I don't hear from you before I am ready to work on that port, I'll go by the Apache License attached to your repository and fork it and port it. My work is normally licensed under LGPL 2.0, which should be compatible.
