This was my aim also.
Hopefully a stable platform to run on.
I don’t need the new features, so would be happy with a fairly static fork that includes security patches.
Bug fixes would be a nice to have.
Someone else may want to build upon that (in another fork?) and include (overlay) some of the newer features, albeit they may need re-writing.
I can’t promise anything, but will try to look at tidying up a few things.
