Distros are likely to care; a Qt BC break requires a mass rebuild of
everything that uses Qt (which translates into lots of users needing to
update lots of packages when Qt changes). Distros may refuse to update
Qt within a distro release as a result, which means users are stuck with
older Qt for longer.

All that more or less already applies to the standard library however
(probably most distros don't accept a standard library BC break without
a mass rebuild anyway), so Qt insulating against BC breaks in the
standard library is maybe less necessary.
