This and many other features need to be bundled up behind a single permission prompt that gives the domain permission to be an app instead of a web site—and that permission should probably come with stricter restrictions on loading third-party resources.

It would be tough to make such a thing work because then every site would annoy you into being an app.

In Chrome, there's already a toolbar displaying that you can install the website as PWA. In addition, a lot of websites already try to stop you from using the web in favour of using the app (e. g. Reddit). So, I don't see this as a new annoyance.

Hence why the invasive permissions need to be paired with restrictions that impose a tradeoff and incentivize sites with a more traditional web page usage model to not classify themselves as app-style sites.

I can't think of a single time I wanted to allow push notifications or allow for my camera or mic to be accessed, but I can at least acknowledge that others may want this.

"Very deep"... is that subtle innuendo?

No. It isn't. And this isn't the place for that.

Edit: I was thinking of simulation gaming, such as racing (forced feedback, hitting the wall), Fishing (fish on the line, rumble as forced feedback, etc)

This is 100% the place for that. On the XBox Live Indie Games marketplace, the top-selling game was always a "scalp massager" game (or "game") of some sort.

I think previous poster is saying this is not really the place for titillating innuendo, or low effort jokes about such, which I’d tend to agree.

And I'm saying that teledildonics is a fascinating and rewarding area of consumer tech that 100% deserves a visible place on HN without resorting to hints and innuendo.
