Ability to lock maxzoom for background imagery

[tawirth]

When mapping for HOT projects, it is often the case that there are different imagery dates at different zoom levels. In these cases, newer buildings are present at the lower zoom levels, but not at the higher zoom levels (e.g. newer imagery at zooms to 18 and older at 19-22). Disabling auto zoom at a lower zoom level allows the new features to be mapped accurately by allowing the mapper to zoom in to the newest imagery. This is currently available in JOSM, but most new mappers use ID. I believe this would significantly reduce the amount of validation work required if the project manager were able to specify which zoom levels to use in the instructions. Thanks! Troy

This has come up before in #2513 and #2564. I guess another way of saying this is, people are looking for is a way to override the maxzoom temporarily for an editing session. (maxzoom is currently provided either by editor-layer-index or we just pick a high value for custom imagery)

Thank You for considering, Bryan. I figured it had come up before. I would prefer that the imagery sources didn't change at different zoom levels, but it seems a common phenomenon. I do think this feature would be a great help, but of course, I don't know how difficult it is to implement. Troy

I also regularly use the disable autozoom feature in JOSM, but in my case I actually use it to prevent the imagery zoom level increasing to the highest for Esri clarity layer as it was recently updated in my area and the alignment is totally different and inconsistent.

There are also some areas where DG Premium seems to return blank tiles at a high z level (around 18). Instead of images it's just black. Locking the tiles at z=17 would solve this.

@tyrasd Any chance to consider this issue? Maybe it can get a "good first issue" label if it's relatively simple (which it seems to be)?
