We have to change it for one reason: Specs need to match reality

Who does?

The dev community decided to improve upon that decision. Council has not tried 
to stop it. After about a year and moderate use (I count over 150 uses in 
eclasses alone) there's no way to migrate back. So the "correct" thing to do 
is for council to vote on it at the next meeting I guess ...

Wargharbl.
Not changing it breaks sourcing on council-approved trees. We can do it, and 
we have to do it if PMS is supposed to have any relevance at all.

That might have been a possible solution a year ago. Too late now.  
(Also, if you want to play semantic games ...
"The interpreter is assumed to be GNU bash, version 3.0 or later."
One could interpret it that any version [and any feature provided by later 
versions] is acceptable, which would allow bash4 features in ebuilds now as 
bash4 is stable. That would definitely not be what you'd expect.)
