19381	Warn users about making changesets with unreasonably large bounding boxes	mkoniecz	team	"==== What steps will reproduce the problem?
1. For start warning about +100km or +500km bounding box would be nice

==== What is the expected result?
https://www.openstreetmap.org/changeset/86588575#map=4/47.65/57.15 https://www.openstreetmap.org/changeset/86601765 - user will get warning

==== What happens instead?
No warning

==== Please provide any additional information below. Attach a screenshot if possible.
For bonus points - do not warn if objects being deleted or their original size was already massive (for example editing country relation will create enormous bbox and it is unavoidable)

For bonus points - warn when user starts editing far away from edits made so far

Partially inspired by feature request made, for some reason, on talk mailing list
