The challenge is that the notification acceptance rate is so low on mobile devices that it makes it meaningless to implement such features [1]. Practically, user is most likely to accept notifications from sites that they interact with a lot. Those also happen to be the sites whose app user is willing to install. Thus, the notification feature on web is not something that a lot of users require.

Not really? [1] indicates that notification prompts actually result in users navigating away from webpages clearly demonstrating that this is a user hostile feature.

As pointed out in the linked article, the stats conflate unwelcome/unrequested notification prompts (e.g. Reddit, which pops up the prompt the first time you open the website (or used to anyway)) and cases where the user explicitly requests/opts in to notifications. I feel like the latter is something that proper web apps that don't utilize dark patterns could make very good use of. Consider the 85% acceptance rate for the camera/microphone prompt; few websites request camera/microphone permissions in the same intrusive way as they request notification permissions, hence it's not declined as often.
