P.S I took a look at wayback machine for landuse=scrub .. https://web.archive.org/web/20110801000000*/https://wiki.openstreetmap.org/wiki/Tag:landuse%3Dscrub
No entry found there. If I could find an entry there then I might be able to justify an automatic change.

From April 2009 I got https://web.archive.org/web/20110312002352/http://wiki.openstreetmap.org:80/wiki/Land_use_and_areas_of_natural_land

And that has natural=scrub, no landuse=scrub.

I see it as 'housekeeping' - tiding up so that things are 'in order', conforming to present tagging practice.

I was told that I have to contact each contributor to advise them of this potential mistake in tagging and the potential correct tag. That imposes a fair degree of work on all, myself I'd rather just change them. But on the other hand contact is good too.

I do not believe OSM has 'everything quite right' now .. so I expect there may be changes in the future too, I hope there are - OSM should evolve.

Hi,
You removed way/460671406 .. that forms the outer of a pedestrian area ...
relation/6805057 now only has an inner ...

Either remove the relation and have no pedestrian area here or reinstate the way you deleted.
