I think you're forgetting an important stakeholder here: humanity. We as a unit need to do things in an efficient way so we can save our limited resources for other, more important things.

Developers and their time matters more for the above since they're a smaller, minority population whose services are disproportionately necessary as opposed to users (who are more replaceable).

From purely a self-centered user's point of view, it doesn't matter, and might even be a negative since they don't get Apple's high-touch review. But it's not like Apple cares all that much about the opinions or user experience of the user either. One positive I can think of is more diversity and availability, there are just many more PWAs available. Another is time saved - if a user can start using your PWA in a couple seconds instead of painfully installing the app over a minute, then over a billion users you've saved very significant time.

I would even argue this sort of time saving might cause "natural" selection.
