Aren't you two forgetting one minor thing, though?

A layout without refs/, i.e. $GIT_DIR/{heads,tags,...}, will force
us to keep track of where the tips of histories are anchored for
reachability purposes, every time you would add a new hierarchy
(e.g. $GIT_DIR/changes)--and those unfortunate souls who run a
slightly older version of Git that is unaware of 'changes' hierarchy
would weep after running "git gc", no?
