Which is of course of PARAMOUNT IMPORTANCE, because signatures right now use almost 4% of database space. That's not acceptable.
(yes, I'm kidding)

% mtn db exec 'SELECT SUM(LENGTH(signature)) FROM revision_certs;'
% bc

...and even this is strictly not true at the current 80 bit security level we're using (1024 bit RSA is around 80 bit of security and 3.2x faster than ECDSA-256p), though it would be actually faster at higher security levels (e.g. ECDSA-256p has 128 bit of security and is 2.4x faster than the equivalent RSA 3072 bits; and produces signatures 512 bit long, vs 3072 bit).
