In an offline discussion with Foteos Macrides, we explored the various
pros and cons of REPOST vs. Idempotent: yes. I'm not sure we've
reached closure yet, but there was a side topic that I thought I'd
bring up:

One of the concerns about bookmarking 'POST' requests, whether
idempotent or not, whether the client warns or not, is that some POST
requests contain passwords or other 'hidden' information.

Even if a POST result were identified as idempotent, clients might not
want to quietly save all of the input data on a hotlist in such
circumstances.

Maybe there's more about a POST result than just 'idempotent' that's
actually useful, as in 'is it safe to bookmark the request'
independent of 'is it safe to redo the POST'.
