No outrage, but I expect this involves picking a new version for minimum
required version, so that you can use things introduced in that version
or later.

Personally, I use pkgsrc which has 2.71, so I am highly unlikely to be
bothered.

What version do you propose as the new minimum?

(If you are just cleaning up and the new configure.ac will work on the
same set of versions, I see zero issues.)
