From the other topic, but I think it better belongs here.
I do not think that is another idea, in both cases I see a need for a curated/clean/release stream of diff’s and planet files etc. that third parties can use to draw tiles. Or does somebody thinks that is no responsibility for OSM and providing such curated/clean/release stream of diff’s and planet files should also be done by third parties.
I see also a need for a unfiltered “dev”/“qa” stream for mappers to see what they are doing and to detect vandalism that ideally is not in the curated/clean/release stream.
Fine to me if OSM does not provide tiles for that curated/clean/release stream but something will be needed so they do not use the unfiltered “dev”/“qa” stream instead as they are doing now.
