Well they're going to be shipping GOS on Motorola and I think some other devices, so basic things like the messaging app need to actually have some polish to them. I really like GrapheneOS overall as-is, but the messaging app felt like baby's first texting app. Not necessarily their fault since it's pretty much straight out of AOSP if I understand correctly. But any time I've installed GrapheneOS, the messaging app is one of two things I must replace every time (the other being the downright bad AOSP keyboard).

If they fix(ed) their messaging app and their keyboard, then they've really eliminated a lot of potential complaints if a less tech-savvy crowd ends up buying future Motorolas.
