I agree that adding these features doesn't really help much for people that
are porting from 2.x to 3.x. However, I can see it being useful for package
developers who want to support both 3.x and 2.x. The more these two versions
have in common the easier it will be to support them both. Obviously, this
means the package might not work with 2.6 and earlier. But some users out
there might be in some situation where they cannot upgrade to 3.x but can
jump from 2.4/5/6 to 2.7.
