[ippm] Re: I-D Action: draft-ietf-ippm-responsiveness-07.txt

[Sebastian Moeller <[e-mail]>]

Dear list,


just a quick note that this update IMHO manages to noticeably improve an already good internet draft. I am typically a bit weary when drafts get longer (I subjectively prefer RFCs short and to the point to match my limited attention span), but here my perception is the draft got deeper it does not "feel longer". I do have a few small nits/questions, am I right to assume these are best added as issues to the github repository?

Regards, and thanks to the authors
	Sebastian
