We should probably figure out how to resolve that display bug, if somebody can create an issue. I think what's going on here is just that J->L added a bunch of server-side bits, and the kernel only implemented (and reports) the client-side ones. So when trying to match the features to a version, it doesn't match *all* of Luminous. We've run into this before but fixing it was slightly irritating, and it's becoming more of an issue so we should bump it up the list to deal with.
