That's sort of what I was asking:  For something that isn't supported in
our TDB-based xattr databases, isn't supported on linux and would only
be supported on some platforms, is it likely that we will come up with a
use for this (more than just that it could be done in theory)? 

(The some platforms thing is important:  protocol extensions that only
work sometimes have far, far less utility than things that can be relied
on).
