Works fine here, on mutter with mesa. Looks mostly like a KDE bug.

You can still theme gtk though, whether it's simply by editing /.config/gtk-4.0/gtk.css
or by using a more in depth app like gradience, everyone using the same defaults actually makes it easier to further tweak.
The problem is when you allow one developer its own applet, every application wants one, and suddenly you have 15 applets. Applications need to figure out alternative design patterns to achieve the same result or sidestep the problem.
There's this saying, out of sight, out of mind, do you really need to have a constant eye on every application? When there's an actual change you get a notification.
In fps games ? Absolutely. By adding a limit you're telling your player to use it, or lose it. Gotta protect players from themselves. Unfortunately it's hard to apply to some types of games, like crpgs which are notoriously bad at giving random shit that you might one day need.
This is a game design failure, it's why max ammo is a thing.
If your code isn't up to par, or your feature isn't relevant enough and doesn't fit "the vision", it's correct to deny it. On top of diluting the project contributed code add a maintainership cost that the random contributor will probably not be footing.
Accept everything in your cake and tomorrow it'll be an inedible mess that nobody wants. It's ok for software to be aimed at different people.
Google has a swath of PR people, devs are always going to be less socially inclined. Devs at google aren't the ones making the decisions. But yeah gnome does throw its weight around, both for good and bad.
Notifications are more effective at displaying a change of status than a tiny icon turning red. What's important to someone is gonna vary on a case by case basis, sometimes getting an email is an urgent notification, you can easily turn off the ones you don't care for or go into DND mode.
Do you honestly think an icon bar like this is a good thing? Look at the colors, the amount of them, how they fold because there's too many... And it's the same shit on windows too. It looks ugly, they're hard to click on, most of them don't serve any purpose... I agree appindicators do serve a purpose, but as it is, i prefer not having them at all.
