When you are doing a worldwide mass retagging, you can't simply go "I have given my argument and am not really in the mood to continue the discussion." . There's a responsibility to bear. 
`lit=yes` is generic. It doesn't say whether it's lighting up at dark only. It would include at least  `=24/7` all the time , if not more. 
`lit=yes` is an initial level of detail. This is affected how most people may not care to add anything more than that. It doesn't mean the Denmark users aren't allowed add `=sunset-sunrise` themselves. 
Your question of `=sunrise-sunset` for eclipse can be asked. But it needs to be asked first, not only after making the edits.
