In addition to Canonical continuing to invest in developing Mir as a platform now built atop Wayland, over the past year Canonical developers have been quietly working on Miriway as a Mir-based Wayland compositor and it’s becoming iteratively more useful.
I’m not entirely sure what its purpose is.
I never knew what made Mir different from Wayland, apart from using a different input system.
The whole point of Mir is to enable the use of Android drivers in Ubuntu (via libhybris) so Canonical can chase tablet sales and IoT fairies, but I don’t know if this information is outdated (aka if Weston can do it too).
Weston has had support for libhybris since version 1.3, which was released on 11 October 2013.
That makes you wonder what’s the point of Mir at this point.
My guess is sunk cost fallacy.
IOT, I think. According to this image of the architecture

I really don’t know and would love to hear more about why Mir still exists.
