Hmmm...I'm not sure if you're asking me "Why do you want to have this
feature in core (i.e. w/o using a module)?" or "Why do you want to
have this feature at all?"

If you are asking the latter, then I fear that we're having a rift; to
me, this feature is so obviously useful that I will need you to
explain why you see it as an issue.

If you are asking the former, then the answer is "I would like to see
this feature supported in a way similar to how we support P5's
$&--that is, it doesn't cost you anything unless you use it.  If this
is the case, then there is no reason that it should not be in core,
and therefore it should not require a use/pragma/etc."
