VRF support? Testing out EVPN at home

Looks like the functionality is purely in a kmod, because when I enable that option I get exactly the same sized image built. Can you validate that finding and perhaps we can include it by default if the size is not increased?
Actually - the sysupgrade is the same size but initramfs grew a small amount:

Only 82 bytes larger tho, which seems negligible.
