Jo, I'm not sure that the GRB layer should be part of the default layer set. It becomes too dangerous people will use it without reading about the limitations.
But anyway, thanks for working on it. Otoh, supporting iD is also important. We can't say "Don't trace from Bing" if people can't use Agiv in iD. For that, we would need a TMS. So that either means setting up a map proxy to convert WMS from Agiv to TMS, or finding some TMS layer available (there are TMS layers for older imagery from Agiv, but I've found none for the most recent imagery). Then, it needs to be added to this repo: https://github.com/osmlab/editor-imagery-index But I'm not experienced enough with imagery to accomplish this. Jo, are you, or is there anyone else wanting to look at this? I think it would save us a lot of problems.
