Say there is commercial interest… it’s all custom work. Having support in the mainline kernel is a fairly small piece of the equation, there aren’t active distributions that support it. At best you’d be putting a newer kernel on an ancient distribution, worse you’d be building a hand made distribution. If they are supporting some old Linux, I think it would be best to patch that kernel if there are flaws or fixes. If there are newer features they are attempting to add, I assert that you probably want more than the kernel like the C library.. maybe a lot more pieces. it’s not easy and it’s a pain but an out of line kernel patch doesn’t seem that bad, whether or not the support is mainlined seems pretty small compared to maintaining the tooling chain and everything else. The support and “new features” is pretty limited too, usb-c isn’t coming, thunderbolt isn’t coming, no advanced power management is coming.
