It totally is: https://developer.mozilla.org/en-US/docs/Web/API/Notificatio...
"The idea of notification tags is that more than one notification can share the same tag, linking them together. One notification can then be programmatically replaced with another to avoid the users' screen being filled up with a huge number of similar notifications."
Apple are the only ones not supporting this, and much of the time with web stuff they have a point, but this one just seems obtuse.
You are right, wasn't aware of it. Looks like Chrome didn't implement this either. I'm not an android user, but to be fair, there is no way Notifications can be grouped like this on iOS with native apps.
Apple groups notifications using on their on-device AI.
So even if it was supported the OS would just ignore it.
