Thanks for considering this, Nick.

At the moment, some of your downstreams have the impression that KEYS
indicates all of the keys that apache might use to sign releases.  For
example, in  http://bugs.debian.org/732450#22 Arno Töll writes:

Maybe you could update the preamble of KEYS to indicate that only strong
keys (and please clearly define "strong" if y'all are making this
policy) will be used to sign releases?

Your 4096-bit key (0x3CE3BAC2EB7BBC624D1D22D8F3B9D88CB87F79A9) appears
to be certified by nearly 60 other keys -- including at least a couple
debian developers and Nikos Mavrogiannopolous (the lead GnuTLS
developer).  I can't speak for all of debian, but i think a strong key
connected by a few paths to other established free software developers
is more reliable than a weak key connected by dozens of paths.

The keys themselves should not be the weak point in our cryptosystems.

(i recommend using full fingerprints instead of keyids if you have to
communicate about a specific key:
