While I understand your point, and I think I agree with it (though I'm almost
on the fence), I wonder if I should explain - I think the argument for removing
legacy sooner rather than later is that by removing the crutch of "eh, we can
just use legacy for that for now", we will encourage development of replacement
GAL features as well as reallocate useful developer time to them, and that
perhaps the temporary incompatibility with some systems and small handful of
missing features is worth the trouble on the development branch --- those who
require the missing features or compatiblity can use Stable for important
projects.

Not entirely sure how much I agree with that, and how many users such an action
would piss off. But I think it is a point worth being considered at least.
Temporary inconveniences on the devel branch aren't world-ending, tbh.
