Comment (by arma):

 git commit 600ef9d5b4faf on my hs-stats branch collects the basic version
 of these stats.

 Here's the initial output on moria1, which had the HSDir flag (but of
 course when I restarted for the new code, I'll lose it).

 Seeing this output made me open #13207 since I bet the "14 descs" will
 grow to a much larger number but that number won't be an accurate
 representation of how many "recent enough" descs I have.
