Nobody is expecting that.  I guess munin is just reporting the number
of files is the upload directory instead of asking the db.

Come on, it's there since a number of weeks. ;-)

I know everything takes time.  My TODO is getting longer instead of
shorter, too.  And I also have a list of little things I would like
the server to do or to do differently.  I have mostly kept my mouth
shut because I don't want to put too much pressure on you.

So far, these values are stored in the file name and could easily be
extracted by the client and put into POST variables on upload.

But, I will put a proposal for v2 of the tileset file spec onto the
wiki once I am done with my current rendering changes.  And after we
agree on that I will implement it in the client.  Then you can
implement the server side and test it.
