Consistency of VACUUM's options seems like a lost cause already :-(.
Between them, DISABLE_PAGE_SKIPPING, SKIP_LOCKED, and PROCESS_TOAST
cover just about the entire set of possibilities for describing a
boolean option --- we couldn't even manage to be consistent about
whether ON or OFF is the default, let alone where the verb is.
And it's hard to argue that FULL, VERBOSE, or PARALLEL is a verb.
