this is true.
but that basically defeats the whole point, which was not needing to
care about these modules any more.
now reality caught up already and it turns out that i broke webkit.
well, what i actually did, i broke bug-to-bug compatibility, which
exposed a pre-existing problem in webkit, as it usually goes.
it would be possible to revert the respective qmake change (and uglify
the surrounding code), but i don't think it's reasonable to enforce this
type of stagnation - we generally accept that code which relies on
undefined or outright broken behavior is broken by fixes.
so how do we go from there? i see several options:
- continue to drag along webkit and the other deprecated modules. the
additional cost of actually doing that in addition to compatibility
testing is rather low with the new CI.
- release further 5.5.x versions of these modules when necessary. i
expect this to be a lot more effort than the first option, so it
doesn't seem reasonable.
- simply accept that it's broken, and tell people to apply patches.
