I don't. I could deliver a diatribe on how even the common arguments for differentiating GET & POST don't hold water. HEAD is the only verb with any mild use in the base spec.

On the other hand:

This is a bigger problem than verb choice & something I very much care about.

There's one, though. The client can tell the server it has a cached version, but that only works (automatically) for GET in browsers. That could have been solved without resorting to those verbs, of course, but it's legacy.

HEAD allows the server to send meta data without the (potentially very large) body. That could have been solved without verb (as if HEAD is a verb in this case!), of course, but it has its uses.
