Meh. The single one AOSP application that I'd actually want natively on my Linux phone is the open source Hacker's Keyboard, to enable a full-sized PC keyboard on the touch screen. Everything else can be left to an emulation layer like Anbox.
I mean, if I'm running Android on the host level and the desktop OS is virtualized or containerized, I'm not fused as long as it's a fully featured desktop environment.
If so, why don't they ship standard full-PC layouts as Hacker's Keyboard does? IME, those are especially useful in landscape mode, or else on larger-screen phones and tablets.

Looks like they're still far from basic feature parity with HK: they don't have key-specific popups for alternate inputs, and are unclear on how to support shift as a "true" modifier key (as HK does) without interfering with their existing UX, which is oriented towards composing text without necessarily involving the application. (This can be especially beneficial on smaller devices, where the "keyboard" can actually be a full-screen view with the only function being pure text entry.) A more PC-like layout would still provide some benefits though.
