The result would be incoherent. Except that I cannot take decisions for
other module maintainers, for fear of being seeing as overbearing and
(paraphrasing) "thrusting changes upon GNOME which would then get
whitewashed as maintainers discretion".

Given that there are no library dependencies, it would always be
run-time detection, as it was and as it will be. No change there.
