> As long as installing PWAs requires user initiation with actions in the browser chrome, and can't be initiated by a link in site content, that shouldn't be a problem with PWAs.
And that’s all anyone is asking for, which would make PWAs equal to native apps in that regard.
Your fervent opposition higher in the thread seems like a different position.
I don't want INSTALL THE PWA spam-prompts everywhere. But, I like being able to open app store links from the browser. My ideal world is not terribly friendly to PWAs. I might use them, but I do not want them to be able to prompt installation actions in the browser. My persona UX is best if they cannot, but if "real" apps can. Second-best would be if neither can (and that's not that much worse—I'd be OK with this). Worst, by a long shot, is if both can.
If both require "share -> install app" or "share -> install web app" (depending on what the site offers) that would be probably my single most-favored solution. Totally fine, both on equal footing. I do not want PWAs to be able to trigger prompts or provide links that initiate PWA installation, even if native apps continue to be able to do so, "fairness" be damned (fairness, in this case, harms my UX because this functionality is guaranteed to be spammy—the "install the native app" prompts are already spammy enough, I don't need more of that). That would definitely make the mobile web even worse than it already is.
What I'm opposed to is letting PWAs prompt for installation. That would be bad, no question. Removing native apps' ability to do so is fine too, IMO, but would also require removing the ability to link to the app store at all to not open up other potential issues. If that's the cost of keeping PWAs from being able to prompt, cool, go for it. But please no PWA "click to install" prompts. No no no.
There is no shouting in these Smart App Banners. The entire user-visible experience is completely controlled by Apple. It is just a passive bar at the top of a webpage that informs the user of the option, which they can dismiss. It isn’t jumping up and down, it isn’t playing loud sound files at the user screaming at them to click it.
What really sucks is when websites like New Reddit provide their own custom modal prompts that cover the webpage and push you to the app, and they’re extremely hard to dismiss and oftentimes these half-baked implementations are broken even if you accept their suggestion to open the app. That type of prompt is not relevant to this discussion, at all. They can do that no matter what you think and no matter what Apple implements. The way you have been talking about these things makes me believe you think those prompts were what is under discussion. They’re not. Smart App Banners are not shouting “INSTALL THE APP!”
I’m personally surprised that Apple doesn’t offer a setting for Safari to disable Smart App Banners, which would be a simple way to stop annoying the few users who are bothered by them. I see at least one safari extension which claims to do this, but since this passive banner is extremely unobtrusive, why bother?
I’m immensely bothered by all sorts of ads and anti-features, but just knowing if there is an app is a legitimately useful thing, so this does not bother me. Even calling it a “prompt” is a stretch since it does not require any action to dismiss. It is a very light “call to action”, of course. If I’m browsing a website I don’t care about and they use this feature, I can ignore it or hide it. It doesn’t get in the way. I'm fairly certain you can even scroll down and the Smart App Banner will automatically scroll off the top of the screen, resizing the website to fill the entire screen.
And that’s all anyone is asking for, which would make PWAs equal to native apps in that regard.
