I understand your position. You have made it clear that you don’t care about other people’s opinions about what should and should not be in OSM. But let’s say that I care about your opinion, and I’m willing to work with people who want to remove my edits. Is it reasonable for me to ask that rather than deleting my edits, people tag them with ohm=yes ? I can search for ohm=yes. I can’t search for, well, I can’t search for deleted things because they’ve been deleted. Your suggestion that I grovel through past OSM data looking for things that aren’t in current OSM is inadequate. At least with an ohm=yes tag, we can have a discussion about what belongs in OSM and what belongs in OHM in regards particular data rather than overweening opinions not grounded by circumstances.
Deletion is forcing one persons opinion on the data set. Tagging initiates a discussion, as should happen in a community.
