[Tagging] It seems that opening_hours:covid19=* tag is a bad idea, right?

There is quite a bit of "most or all of us are mostly or completely correct" here.

To add my 2 cents, "opening_hours" are "opening_hours," especially if they are frequently updated as the actual opening hours change in the real world.  If an author edits a tag (consciously or unconsciously) to include some information about COVID-19, that isn't any great harm, especially if true.  But it does potentially restrict a business from changing their opening hours for whatever reason (which is an artificial, false restriction), and having OSM possibly wonder, "hm, did those hours change because of COVID-19, or did they 'simply change?'"  Because the reasoning behind the hours being something different isn't all that important (in my opinion), including data in OSM about opening hours being attributable to COVID-19 has diminishing value, much of the time, I'd say, right down to zero.

But if people want to add these data, with specificity, it isn't wrong to do so.  It simply may not be relevant, and it "clouds" the usefulness of the data going forward.  I wouldn't say "bad idea," I'd say "of very limited usefulness."
