Definitely... that's part of the reason I chime in when this topic comes up. Having done both Linux and mobile development, I don't believe that the entirety of the answer is going to be 'just throw a more powerful SoC in the device'. Sure, that will help to a degree in some areas but there is a lot of work that has been put into iOS and Android to achieve a balance between battery life and performance that most developers who have only worked in/on Linux haven't appreciated. Which is understandable since it wasn't 'their' problem... now with the Pinephone/Librem 5, it is.

Something I have found worthwhile has been listening to the UBports podcast over the last 6 months or so. They really do seem to be 'getting it' faster than most re: what's left to be done. That's partly because they're in the rather unique position of coming from a place of having the Android kernel (which isn't just a vanilla Linux kernel) do a lot of things for them (i.e. UBports on Android phones) and now that they're running on bare metal (i.e. UBports on Pinephone) with (mostly) the same code base they are able to see 'oh, yeah... the kernel and/or apps need to be able to do Y' in order to replicate the functionality they get on Android phones.
