Certificate validation isn't needed unless the attacker can do a direct MITM
at connection time, which is a lot harder to maintain than injecting a
client.reconnect. This, combined with your concern about up to date
certs/revokes/etc, is why BFGMiner defaults to TLS without cert checking for
stratum.
