I do. Unfortunately I've been swamped, and still am, with other stuff,
and have had zero time to work on it :-(.
My current plan is to finish the FSM rewrite for/during the September
commit fest, and submit a patch for dead-space-map driven VACUUM for the
November commit fest.
My original plan was to enable index-only-scans using the DSM as well
for 8.4, but it's pretty clear at this point that I don't have the time
to finish that :-(.
