I have no idea if Tracker uses just one huge file for everything or if
it can use one file per application/domain/whatever (and in any case
that's an implementation detail not terribly important for this debate
IMHO). My only point is that something like tracker-store is already
useful even if you don't ship a single filesystem miner with it. You
could even argue that in many cases it's better for the apps to feed
the data directly to tracker and cut the middleman of writing it into
the filesystem for miners to find it at a later point.
