Without any references, it's hard to know what you're referring to 
specifically.  However, I *think* you're talking about the Intel e1000 
ASPM bugs.  Those bugs were in the Intel NICs, and had nothing to do 
with decision making in the Fedora project.  If you're convinced that 
those features have no business in server class products, then you 
should provide that feedback to the hardware vendor who enabled ASPM in 
their BIOS (had they not done so, you would not have been affected by 
the bug).  I think you're upset at the wrong people, though I understand 
your frustration.  I was affected by that bug, too.

If you're referring to something else, I'd be curious to know what it was.

Well, considerable effort was made to provide discernible benefit. If 
you find time to look at it later:

I doubt you mean to imply that you'd use OS X as a server.  No one does 
that.  Even Apple uses Linux for its servers.
