Interesting. As a dwm guy I was unaware of ewmh standards. Have you used dwm to be able to compare? I love dwm, but it does behave in some cagey ways at times.
Just this morning my oldest daughter who is almost 4 asked me to go to the basement before school and I said I would turn on the light and get it ready for her, but Daddy wanted to say for a few minutes on the couch.
She said “Ok dad, here’s bun bun (her comfort animal) so you can snuggle and feel better”. It was so selfless I went with her anyway and she said “Did you know I love you, dad?” On the way down the stairs and it was great.
But she was totally emotionally intelligent enough to say “daddy isn’t feeling good, I’d like to help him” and I think that starts MUCH earlier than people think.
