To facilitate this, add a DISTRO_FEATURE and talk to RP/TSC about getting the badge added.
The badge process (which is under review) is currently documented here: https://www.yoctoproject.org/ecosystem/branding/compatible-registration/ For YP internal layers, perhaps that process is not required? The marking of layers as YP Compatible 2.0 in the layerindex is done based on PASS of tests in "check-layer" and "check-layer-nightly" Builders on the AutoBuilder.
