We had these two enabled for 1.2.x releases too. I disabled them for the
1.3.x releases because I though no one would use them. But apparently,
some people still do need those.
(and nobody complained about patents back then).

I don't know about those patents. But as far as I'm concerned, those
ciphers are only used if the server requires them. So if they're
patented in your country, just configure the server to not use them.

And you maybe don't want to know my opinion about patents... :)
