Right, but my point is that the amount of effort required to just get the multikernel fully running on quirky phone hardware is quite a lot, and then you have to set up a lot of plumbing for both userspaces to communicate across kernels (i.e. you'll have to write driver shims for a lot of things). It is probably easier to port software to ubports.
Yah, I mean, thats true. I guess I was hoping the multi kernel thing would be more of a 1-time development effort that would work across phones, so once you got it set up it would help all phones accomplish the same thing. I'm not a kernel dev though so I have no idea in reality how this stuff actually works under the hood.
There would be shared parts for sure, but knowing the nightmare that is phone boot environments I feel like it would need a lot of effort per device still.
