Not for the bug fixes because they will likely to be backported in all
versions. (3.3 and 2.7)

Now for new features, if pip uses the latest 2.x and the latest 3.x
versions, you will get them.
I am not sure why you would have to ignore them. You would probably want to
use the new features when they are released, and still make your code
work with older versions.

There's no way for the new features to show up in 3.3, is there? You can't add them to a micro release, and you can't replace a module in the standard library. I think that's Ian's point.

But that's no different to pip using *any* standard library module. If you want to support Python 2.4 you can't use os.path.relpath (or you have to provide it yourself anyway) for example.

pip could use the new features in 3.4, and it could get the new features in 2.x if the users were willing to install the updated library, since it's not in the stdlib. But for 3.3 you'd be stuck.
