I can't find any precedent but if we *really* want then probably we
can get the "compiled with" Qt version from QCoreApplication
(QCoreApplicationPrivate::app_compile_version).

1. Allocate the resources only if the version >= 6.4.0
2. Probably add a "TODO: remove me" in 6.x.0 (e.g. after the next LTS)
