Technically this is correct, though I don’t think the understanding of the users is the same. For a normal user currently there are two links in the Edit-menu, one is directing to iD the other one to jOSM (since P3 and Merkartor are more or less just a niche). It’s not obvious that only one of the two links are part of the Editor Inclusion Policy.
I would say that all items should be covered. I see no issues in restricting the evaluation to the editor as supplied or recommended. Someone sufficiently motivated can compile their own version of any desktop editor which, by default, will do something the community believe should not be done. That’s different than the case where an editor, as supplied and recommended, does stuff that shouldn’t be done.
Apologies if I missed it, but I was wondering if there are any updates on the acceptance of the inclusion policy. I didn’t see it discussed in the January minutes.
