Traditionally the time for bike shedding the exact syntax is much closer to stabilization.
Because Rust is allowed (at this sort of distance in time) to reserve new keywords via editions, it's not a problem to invent more, so I generally do prefer new keywords over re-using existing words but I'm sure I'd be interested in reading the pros and cons.
