Yes, that's what you prefer and I'm not discussing with that.

And you can even achieve it with the current definition of entires like this:

M: <my devel mailing list> (no bug reports please)
B: https://bugs.freedesktop.org

What I'm saying is that for the other subsystems that want to use B: that
simply need not mean "preferred", but "alternative".

Well, I didn't say what this implies.

It looks like you are taking what I said as offensive somehow, but that was
not my intention.  Sorry if it sounded like that.

Which is exactly what I did (or at least that was my intention).

No, this isn't what I'm trying to do.

I'm trying to ensure that the B: entries I added will not confuse people in the
end after the change that you are proposing, because they are not supposed
to mean "you should file bug reports there".  They are supposed to mean
"you can file bug reports there", or more precisely "if you file a bug report there,
someone is actually going to take care of it".

So basically, the introduction of B: as I did it changes the bugzilla.kernel.org
default for everybody (which you don't like too) into "no default", as far as
bug tracking systems are concerned.  Which addresses the problem
with the general bug reporters' expectation that all bugs submitted to
bugzilla.kernel.org will be taken care of (which is not the case).

Your proposed change takes it further to specify a preference which clearly was
not my intention.

I really wouldn't like all PM bugs go to the BZ, for example, because for some
of them this is just overkill.  Also if people see problems during development
and not in production, reporting them via the M: list is more natural.  And I
could give you a couple more reasons here.

Thanks,
Rafael
