OK, I'm one of those "users".  Read that as sysadmin of a Gentoo system.
Sysadmin carries some responsibility for knowing how the system is set up,
particularly as it pertains to security issues.  I don't take that
responsibility lightly, nor would I expect anyone to seriously recommend
that I do so.

I would **NOT** appreciate portage taking upon ITSELF to CHANGE my USE
flags behind my back!!!  Count this as one vote for emerge-stopping
errors, NOT warnings that may or may not be seen in the middle of a string
of emerges.  Yes, I use pretend (or more generally, ask), and would
normally catch a repeated emerge there.  However, I still don't want use
flags being changed out from under me.

Of course, as already mentioned repeatedly, having a depend resolution
time failure would be better than EITHER that warning or failure after a
string of depends have been merged.  I agree there (what's not to agree
with?).  However, regardless of whether that's possible, if a use flag
needs changed, I want an error spit out to that effect, so **I** get to
decide whether to change it or try some other package that doesn't require
changes in my use flags.  I do NOT want it simply changed, at the whim of
portage, regardless of whether there's a big warning before it happens. 
If a use flag needs changed, *I* want to be the one changing it, on *MY*
system.
