I think it is important to not get hung up on things like kernel
versions and boot loaders. The nature of the ARM platform is such
that you are inevitably to need more than support for one kernel
and boot loader. But IMO that is a relatively minor obstacle to
adoption at the moment.

If the device ships with a kernel that works, there is nothing at
all stopping you from using that kernel to get the EL6 or EL7
userspace up and running on it. There may be ideological reasons
why that is bad, but it is not a practical limitation on the
ability to use the hardware.
