Have you considered using base/feature_list.h instead? It provides the same
ability to have an entry in about:flags as well as allows to later enable this
via a server-side experiment without any additional code.

Thanks, I will take a look, didn't know this was a thing. I don't see it ever
used in Chrome OS core UI, probably just lack of awareness.
oshima@, do you have a feel for this one way or the other? I've used a regular
flag mostly because this is how we did "top-chrome-md" flag.
