AFAIK, lowzoom stitching is triggered by tile uploads that went
through the request queue, that's all.

Changes of oceantiles.dat won't trigger tiles to be re-rendered and if
you fix coastlines by only reversing their directions or closing gaps
and not changing any of their nodes, the auto requester will miss
those changes as well.
