There's almost a guarantee that it will NOT be backported to 2.7,
actually; it looks like a completely new feature. But if you're
interested, you might be able to apply the patch to a backported
argparse, such as:

https://pypi.python.org/pypi/argparse

Or just patch your own local version, but that's a bit dodgier.

If you're willing to migrate your code to Python 3, and you want this
feature, post in the tracker issue; even better, help with testing the
patch. The patch was updated for Python 3.5 roughly a year ago, and I
suspect that that version will still work; the lack of response after
that suggests that nobody has the time to test it and make sure it
works in all cases.

Since argparse is written in Python, you don't even need to play
around with a C compiler to test this. It's a nice easy thing to play
with - have a shot!
