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.
