I see your point.   Maybe the BPF one could be useful as a cross track
discussion, though I'm not sure the fuse side of the design is mature
enough for that.  Joanne, you did some experiments with that, no?

I think the major show stopper is that nobody is going to put a major
effort into porting unmaintained kernel filesystems to a different
framework.

Alternatively someone could implement a "VFS emulator" library.  But
keeping that in sync with the kernel, together with all the old fs
would be an even greater burden...
