[Tagging] noaddress=yes and (possibly) implicit buildings

[Tobias Zwick]

The discussion has been revolving around earthquakes in Croatia mostly, 
so I have to ask:

Is this still about the proposal to let StreetComplete...

1. ask its users for the housenumber of every building=yes (worldwide)
2. tag noaddress=yes on a building if it has none (cause it is a
    shed or whatnot)
(3. remove noaddress=yes if/when that building is later tagged to be a
    type of building that usually has no address (like a shed or whatnot)
    via the app)

...?

This behavior for Streetcomplete was proposed in
https://github.com/streetcomplete/StreetComplete/issues/2464
and this mailing list discussion was created as a response of me saying 
in that ticket that I think such a behavior of the app would be heavily 
critized if implemented.

It's nice to hear that apparently there is not really an opposition to 
that behavior, but I fear that may be the case because in this 
discussion it sounds like this is exclusively about some humanitarian 
mapping in a limited region (and time).
