Yup.  (In our design documents and specifications, they're called
"directory caches.")

Please see proposal 146 for an initial design here back from 2008, and
the discussions on #572 for a list of obstacles we ran into the last
time we tried to implement it.  Still seems worth doing to me, but
there are some remaining issues to solve there. Designs welcome. Code
also welcome.
