ok() also supports lists, while missing() doesn't, is this

For ok() with a list argument the return value is unambiguous:
it's a series with 1s for observations where no values are
missing, 0s otherwise. With missing() it's not so clear what it
should return if given a list: 1s for all missing, or for any
missing?
