Your argument, out of everyone else's, is the most sane. So lemme point this out:

You're right. There's not a lot of good reasons I can think of. The best argument I've been able to come up with is ISP-level caching of HTTP traffic, which may save on bandwidth. But my host doesn't even charge for the measly amounts of bandwidth I use, so that's certainly not a concern.

Modern servers have HTTPS hardware-acceleration in the form of AES-NI, so it doesn't even use much more CPU power to use TLS these days.

So really, bandwidth savings from ISP-level caching is the best counter-argument I've got. Which is to say: not a very big concern of mine.
