1 and 3 seem like strange advice. I don’t know much about PWAs. Why would you want to do these? 1 seems user-hostile, and 3 would make your app feel broken on iOS.
The reason for 1 was actually my mother who tried the PW, had her phone set to a different language and always triggered the translation overlay ;).
You may well have compelling reasons, I assume each of these is a response to an issue you encountered. But since the article doesn't present them, it leaves the audience scratching their heads and comes off as needlessly disempowering your users. These definitely aren't things you should be doing by default in every PWA, as "checklist" would imply.
If I installed a PWA and I couldn't pull to refresh or select text, I would probably uninstall it.
The points you made about specific issues were good though, like notches, favicons, and mimetypes.
I'll take that feedback with me for future note-to-self style blogs :).
