It does seem like a boil-the-ocean "fix". The entire planet has been kludging this with GET or POST as appropriate for the entire lifetime of HTTP, and now there's a proposal to do something that looks identical to POST but with slightly different semantics? So in exchange for solving a problem that's been dealt with (if not perfectly) forever you'd need to convince the entire world to adopt a new, incompatible mechanism? I'll give this one as much of a chance as BEEP.

You've never heard of BEEP? Well, that's why.
