Again: if someone thinks that encrypted connection is a bad idea, do not use it, miner allows you to do it, I doubt you will ever notice 0.5% difference in your income. I'm not going to remove plain connection, restrict pools, increase fees, etc, there is not any conspiracy theory or evil plan. It seems some people have too rich fantasy.
In my opinion, ability to encrypt connection as an option is a good feature (and I'd like to support it a bit by reducing devfee), so I'm not going to remove it right now, though if I see that noone uses it I can remove it in future. Actually, I think about adding this feature to dual miner too, but now I'm not sure because here I've read a lot of ideas about bad sides of encryption, which looks really strange for me. Don't forget you mine cryptocurrencies, they all consist of pure encryption

Please, don't forget about some users are happy to have SSL connection. At least, they don't want by any reason that anyone between them and the pool could read the data transferred. They don't want anybody expect, that it is mining. They don't want anybody to steal their wallet number and so on. So, an ability to use SSL is generally good.
