It's not just mobile web. You need good accessibility--especially for keyboard--for this to work. But a lot of developers don't make their sites work without a pointer device. This is a problem on the web at large though. For instance, I needed to get a BIOS upgrade for my mouse issue on my Lenovo laptop, but their support site a) required JavaScript and b) wasn't using tabindex or keyboard accessible buttons/links to navigate it. Why this is required to get me a simple ISO or zip is pretty ridiculous. I should be able to use a TUI browser to get such downloads for my device and it doesn't require any interactivity. Beyond this, PWAs aren't the most popular because of Apple if I'm speculating. The PWA experience on Apple's OSs are so handicapped that it's often seen as a waste of time to develop for as Android users are the only ones that might bother installing the app and desktop discoverability is horrible (Fx stopped support for SSB before it even went to stable). Also there isn't a FxOS or KaiOS system that is actually used in the anglosphere where most developers still come from so the need to support is overlooked.
