This strikes me as a pretty bad idea. I map in NYC where we have lots,<br>
lots, lots of nearly-square buildings with official footprints imported<br>
from the city's open data initiative. When a mapper not familiar with<br>
the history here gets a message from iD (which, to many mappers, is<br>
indistinguishable from getting a message from OSM itself) encouraging<br>
them to square a building, they'll do it because it seems like the right<br>
thing to do. So the official, highly-accurate footprints are lost. And<br>
adjacent buildings with shared nodes are also distorted.<br>
<br>
If I were to communicate with this mapper and say "Hi, welcome, please<br>
don't square the buildings" it will simply be confusing because the<br>
official editor, hosted at <a href="https://www.openstreetmap.org" rel="noreferrer" target="_blank">https://www.openstreetmap.org</a>, told them they<br>
should.<br>
<br>
JOSM's validator used to flag nearly-square buildings here, and it<br>
caused thousands of unnecessary and inaccurate updates to building<br>
footprints. And of course people doing these thought they were doing the<br>
right thing -- if the validator says there's a problem, there's a<br>
problem, right? Fixing it is helping the map!<br>
<br>
I'd hate to see iD go down the same road. And I certainly don't want to<br>
mass-tag all of NYC's imported buildings with nosquare=yes.<br>
