But I'm curious how much download weight matters, outside of as a proxy for "how much bloated ad bullshit is hiding inside the app bundle"?
I'd wager the difference between a 2KB PWA and a 5MB or 30MB native app download is relatively insignificant — in storage space, in cellular data use, in initial download time — to your average user when compared to streaming a film on Netflix or downloading a F2P game with 100MBs to GBs of assets.
(where "average user" is assuming most of these apps are only localized in English and only available in largely-western countries — totally get how the story is very different in emerging markets)
