Re: [nfsv4] Proposed Working Group Charter

NFSv4 has been working outside the charter and is now rechartering to
reflect the current situation.

No objection.

> So, my understanding is that NFSv4 wants a revised charter to match the
current work efforts already underway, but doesn't need to add additional
milestones now, is that right?

Yes, but we do need the option to add small milestones without another
rechartering.  In other other words, while there is no problem withr
reducing those paragraphs, there would  be a problem if they were reduced
into non-existence.
