I agree. Solving #3 is terrific (because it frequently bites you when the sender is someone you don't know particularly well... certainly not well enough to ask them to resend using a third party messaging app). I don't really care about #1, although I guess Google's answer would be "use Chat", which is absolutely ridiculous since it no longer has an interface to SMS/RCS like Hangouts did. This is a gaping hole in their product strategy, imho. #2 could be solved by Apple if they want to, or else we'll just continue to struggle along with a need for several different messaging apps for different social contexts. It's not like Whatsapp, Telegram, Signal, etc don't work. Another solution Google could perhaps pursue would be to license one or multiple of those to include in the default Android install, but I don't see that happening without regulatory interference.
