The references you cite seem all to focus on the issue of how to extend
HTTP. The issue at hand, however, is about using POST to emulate an
*existing* HTTP method:

I see this as a very different issue. One discussion about adding
functionality that is missing in the Web and another is about whether to
reuse the functionality available on the Web or ignore it and rebuild
it.

When you use POST to mean "MYFOOMETHOD" you sacrifice specificity to get
reuse of infrastructure. When you use POST to mean GET you undermine
existing infrastructure. And in my mind, caching is the least
interesting thing you lose. Hyperlinking and URI-based addressing is way
more important....
