From #18140 skyper in comment 40:

For opening_hours=Mo-Su,PH 10:00-21:30 I get Opening hours syntax - Holiday after weekday at line 1, column 10

which is to strict see ypid23's comment 10 on #18807 and not human readable

I would say, this is another case, where we need a strict variant and a relaxed one and where the relaxed variant is used in JOSM.

Thank you!

Now, I am puzzled. The warning comes from "Mai" German for "May". So no issue but a no human readable message and the former autofix is missing.

How to handle these missing human readable warnings and the autofixes.
