I wrote an article about some of the fuss we had to deal with relating to redirecting to https.
we dealt with some of the internet archive hiccups, too, but these were more to do with changing a website rather than anything having to do with https.
Another thing to remember is that it doesn't do much good to deliver html over https if you need graphics or scripts that for one reason or another require http. I expect planet.code4lib.org, and perhaps some of the other sites would be a lot of work to switch over, and they might not actually work.
