Yes. Twisted does, in various MIME-ish places (IMAP, SIP), although not in HTTP from what I can see. I imagine other similar software would as well.
One issue is that you don't always have a string literal to work with. If you're proxying traffic, you start from a mis-cased header and you possibly need to correct it to a canonically-cased one. (On at least one occasion I've had to use such a proxy to make certain buggy client software work.)
Of course you could have something like {b"CONNECTION-LOST": b"Connection-Lost", ...} somewhere at module scope, but that feels a bit sillier than just having a nice '.title()' method.
