Looks nice and simple to me.

The trick of adding foo-s and foo-c symbols to the kex_algorithms list
could perhaps be reused in case we need to negotiate support for aead, to
enable different rules for algorithm negotiation (including the rules
for first_kex_packet_follows).

I still question the utility of this extension. I would expect the common
case will be a large list of algorithms, and the the client needs to
send a PK_OK request for each key it has anyway.

But I don't object to it if others find it useful.

Maybe "userauth-sig-algs" or "publickey-algs" is a better name, to make
it clearer that it is related to publickey userauth.
