Bob,
 The RSVP directorate will not, of course, decide the fate of these documents. Our job is to review documents and advise the TSV ADs and TSVWG chairs. I'm just trying to jump start that process, so that when the authors show up at TSVWG, (a) the chairs will be able to say whether it's even worth the time of the WG to hear a presentation on the draft (b) there will be at least a couple of people in the audience who have read the drafts.

 For the record, all 3 of the drafts mentioned below were presented at IETF 76. The authors have asked that they be taken on as TSVWG items.

Shouldn't we raise a similar bar for these drafts, rather than pick up "a few drafts floating around"?

Given that TSVWG is the place for RSVP CAC extensions, yes, I would think TSVWG is the place for it. It's a very small draft basically defining a new codepoint (Resource Sharing Remote-ID Association) with a small behavioural change (only treat this Association-ID as binding on the Resv, not on the Path), so I don't envision any significant backpressure of the form "this is not a small change to RSVP".

Both relate to the issue of reserving an appropriate level of resource (e.g. bandwidth) in a single round trip when it is not known in advance how much resource is available. This is quite helpful, for example, in a video conferencing application that has a choice of codecs. The polk draft in particular was (I think) a catalyst for the RSVP discussion in Anaheim because it seemed to be stretching the scope of what has normally been done in TSVWG for RSVP maintenance.
