K. HN is not your personal search engine or whatever. That’s not how social networks work. You aren’t just going to get crickets if nobody has what you’re after, which seems quite likely given you could count on one hand the number of organisations that could reasonably be in a position to have this data, and given that you would’ve searched before asking this.

It sounds like you’re trying to backsolve for a desirable answer. You can make quite educated / justifiable inferences, not much guesswork at all, to come to the conclusion that the numbers are for most intents and purposes immeasurably small.

Why would PWAs reasonably be used by anyone other than idealistic nerds? You’re kidding yourself.

But they are interesting, so I’m glad they’re posted.
