I think otherwise. In POSIX mode Bash should at least print warnings
about features POSIX lets implementations provide but doesn't mandate,
like function, select, [[, etc.
That would be a far bigger change than just allowing process substitution.
Also, there is already a good shell that does this: yash
<http://yash.osdn.jp/>. Its POSIX mode is deliberately strict and
restrictive and does not allow any non-portable functionality, so it's a
really good compatibility testing tool.
Then there are also shells that simply don't implement much more than
POSIX, such as dash. They're useful for that as well.
So I don't think bash needs to fulfill that function. Bash's POSIX mode
has always been simply a way to run POSIX scripts, with or without
mixing them with bash scripts.
