May I ask to avoid HWC2 only implementation?
The main reason is not all GPUs support
drm_hwcompser (as discussed in another thread).
To continue supporting these GPUs we need to
keep using HWC1 version of SurfaceFlinger.
So it's better to keep the code compatible with
HWC1. At least make it be a compile-time option.

Personally I have a patch to make
HWC1 vs HWC2 a compile-time choice
of drm_hwcomposer.
I can submit it if it's acceptable.
