I'm good to use DISTRO_FEATURES_FILTER_NATIVE, but it was less the mapping
of vcontainer -> virtualization I was going for (although I did like the
simplicity of just checking one), it was the yocto compat question.

Doesn't that change now make it an unconditional update to that variable
(and everyone that had meta-virt in their layers now gets those two
variables filtered )? Or is by the native of it being distro features there
is special handling and it won't cause compatibility issues ?
