Yes, that is intentional as there are hardly any captionless tiles in the new system yet, and there didn't use to be a fallback system until very recently. Now that we fallback to legacy "captionless" tiles, I will start using that.

Some are old remains when there was no legacy tile fallback, and empty legacy tiles would also result in unknown tiles. It's just a matter of time to sort that out :-).

You can still upload lowzoom tilesets spanning from z6 to z11 manually and they will be displayed. Maybe I will try to implement a "blacklist" of areas that people want to create manually

I just needed *something* to display, so I stitched together what I had, which also gave me some idea of where tiles are missing. Now that tile-fallback is implemented, lowzoom stitching would work -unless the legacy tile is blank, which currently results in an unknown tile.

It sure needs some more work until it looks good, but I think it might be the right approach. If people want to continue to do it client-side we can always do that, no problem.
