Right, I'd still say that this is the same as with previous releases.
Overhauling the whole rpc infrastructure, adding smb2 support, etc.

Just claiming "yes" is not enough. ;)

Right, but again, this is no different from previous releases.

Ok, we can go back and forth saying "yes" and "no".
Without proof or examples this will lead nowhere.
I have not heard concerns like this from OEMs, and I also
know a few. Most of them seem to move to 3.6 just now.
All this is of course difficult to prove with examples in
public. Maybe we should have a private chat on the phone or so. :)

Right. It was precisely like that before. Which does not mean we
can not improve our mode here. But I don't want to have 4.0 being
promoted as the unknown evil out there that makes us backport all
sorts of nifty fileserver features back to 3.6. This would
definitely be the wrong sign!
If we are convinced that what we work on in the fileserver area
in master at the moment is good and we want our users, especially
OEMs to use it after the year or half of stabilization that they
need anyways, then should we work against it by "officialy"
backporting patches into the 3.6 release? I don't think so.

I think it would add a little more safty. But effectively
it would still be open for everything.
