That would be a showstopper for now, IMHO. Doing it with maintainable open source Linux drivers is the hard part of having a viable device, from everything I've seen.

Another concern are that I can't find who the developers are, nor even definitively what country they're based in. (I don't see it on their About Us page, ~~and the GitHub repo contributors are hidden.~~ I saw a reference to Sydney, but unclear.) (Edit: my mistake regarding GitHub contributors; they aren't hidden)

Also, it would be nice to have the option of a better hardware provenance than a generic whitebox(?) phone from some unidentified manufacturer in China. Even for individual hobbyist users, and certainly for corporate ones. (This is why I'd like hardware options combinations like Purism for the premium device, and a cheaper device that runs the same software but is still from a brand that at least has a reputation to preserve, like Pine64 or (ha) Google.)

Github repo contributors are not hidden.
