        information that would be nice to be able to tag: have been here

        supply point is still operational can be of great interest (When

              <div class="gmail_extra">Volker, do I understand you
                correctly that you propose to add a specific tag for
                every other tag which says when it was last checked?
                Like amenity=foo, amenity:last_survey=1985-04-01 ? So we
                must not add default tags because we can have a tag
                lanes:last_checked=2018-03-23 which implies that the
                number of lanes is default and must not be tagged
                explicitly?<br>

              <div class="gmail_extra">Sounds like a method to increase
                history bloat. I could check every minute that my house
                is still there, for example, and upload the result. ;-)<br>
