Hello I hope this is the right way for a proposal.
Mostly to @patdavid.
Maybe you have, maybe you dont have heard about the nodal compositing program named Natron.
In a nutshel it is the free and open source equivalent to Nuke, After Effects or Fusion. Its comming very far and even got Gmic implemented 
https://natron.fr
After some changes this year the Frederic Devernay from the core development team wrote this thread today.
https://forum.natron.fr/t/building-a-community-managed-natron-ecosystem/2150
And my thought was that like the Rawtherapy,-Gmic,-Darktable communitys found their home here, it would be great to welcome the Natron community also here.
This was Frederics response:
https://discuss.pixls.us/ looks like a very nice solution! GIMP, Natron, G’MIC and RawTherapee share many components. Do you know how to contact Pat and ask if it’s possible to create a Software/Natron category?
So here I am, trying clumsy as ever, to bring the communities together.
