As for ath79, while many people agree that there should be a migration script/mechanism, it's hard to finally get one (since designing it is a much bigger problem than it seems at first hand).

With mt7621 having started the party without a migration script (as this would have just stopped the whole thing, I think I commented in the PR about it), others followed suit quickly. I do not see why lantiq should be treated differently here.
However, note that this is my personal opinion, and I cannot judge specific circumstances that might apply to the lantiq target or its subtargets.
Again, personally, I do not expect any substantial progress on the migration subject - at least soon -, so I do not think we should delay kernel bumps (which are complicated and big enough for themselves on large targets) just because of that.
