While it's not perfect I've been investing more time into learning to live with grapheneOS. I can run Emacs and clang on the go. It's a better start that won't turn into a paperweight.

ClockworkPi's DevTerm, uConsole, GameShell are constantly sold out [2]. Hackberry Pi, constantly sold out.
Jolla's strength is SailfishOS which is a successor of Maemo/MeeGo. It is a Linux-based solution with a good, gesture-based UI with Android emulation.
GrapheneOS has nothing to do with any of these projects. It is software-only, for Google Pixel devices, and it has a specific strength (security) no other OS/HW combo comes close to.
The strength of a modular smartphone is, it is repairable and you can physically alter its features without changing form factor, like Framework. For smartphones, I believe a Fairphone is very modular, and smartwatches Pixel Watch 4 (but it only runs WearOS).

7 hours is not bad, considering my iPhone 13 mini can only last for day with occasional usage.
Librem 5 and Pinephone didn't fail to deliver.
> They make great pet projects but fail at what most mobile phones do great which is provide a computer I can reliably and safely take with me in life.
And I can't speak to the Librem 5, but the I'd say the pinephone did in fact fail to deliver a reliable daily driver, remaining merely a pet project full of rough edges.
