Because we work hard to minimize our dependencies and make them as
non-onerous as possible.

At a minimum, I think it's fair to say that the burden is on you to
justify what it's worth bumping the version number. If there is some
major speed or performance advantage to using the newer API, maybe
we'll consider it. But if it's just a few extra lines of code to work
around it, then it's better to write those extra lines of code rather
than potentially force users to upgrade packages they're otherwise
happy with.
