have you been talking to anyone on the UX side about this? i know it's just
chrome://flags, but i'm wondering if "lucid sleep" is the name we want to use
when exposing this publicly or if we want something that's less cryptic. "lucid
sleep" has always sounded weird to me; "lucid dreaming" is the actual term
that's commonly used.

kuscher@ is probably the first person i'd ask about this, but he doesn't appear
to be online right now. i asked kanliu@ and he said he's going to ask around.

per kan: "alexandra will come up with something else to describe it without
using a name like lucid sleep"
