That's if you believe the Google thing that it can't be done any other
way. Which other vendors don't seem to be agree with.

Well actually there is a much better simple reason. One of the things you
get by using a standard kernel is the ability to dump a true Android
environment onto another device that's running something else as well.

I don't quite understand why people play some of the strange games they
do but being able to dump them on arbitary Linux platforms is no doubt
useful.
