HellMap
I see what you mean, you'd like the map to be "clean" and without notes. I mean I totally understand.

But I'm personally actually of the opposite opinion. I think we have very few notes and almost no one uses them (majority is from StreetComplete and such). I think half my notes are commented or closed by yourself. I'm actually stopping myself from making way more notes in places I know are wrong or out of date, but are not important enough or I don't have anything to add except "needs survey".

I also think that needing survey and needing aerial are both valid reasons. If a change is so new that it need an aerial update, then GPS tracks (and Mapillary) are also going to be few, if any, and inaccurate. A survey just cannot place things accurately enough.

But anyway, I think you actually surveyed all the major things here, so now it needs micromapping just like every other place. I'll probably bike here at some point or just use Mapillary. So there's probably no need for a note.
