Silent, no. But saying "can't control... certain instances"
explicitly would be fine. I'd be even happier with an
explanation of what such an instance might look like, but don't
see that as a requirement.

It's up to the server to decide whether it provides strong or weak
etags. And it's also up to the server to decide whether you can use them
in a conditional PATCH request (RFC 2616 disallowed this, but HTTPbis is
lifting that restriction, and furthermore WebDAV never had it).
I think not stating this explicitly is the simplest approach (as this is
true for any HTTP method), but I wouldn't object to have more text
either (as long as that text wouldn't have to revised when HTTPbis is done).
