They use the libhybris, they use the work done on wayland (without have helped in nothing, as usual) and, at the end, they will have an ugly copy of wayland that nobody will use because it will passable of break compatibility every time that canonical will need to modify it and without have care about the others.
I'm sure that MIR will works good for the canonical needs, because is based on the excellent work done by the wayland's devs.
Yeah, they are famous exactly for that philosophy.I like that many of the new features I read about are the ability to test and analyze MIR while they are still developing it. One thing Canonical is doing right is doing thier due diligence to make sure MIR and Unity8 are well tested during thier development and not just tested after development. Get the bugs out now while they are easy to see and not coded around.
How many release to have an accettable shell? lol
