The distinction is only important when = `auto-revert-avoid-polling' is set. For example, we could have, say, = `buffer-auto-revert-by-notification' take the values nil, notify-only = and notify-and-poll. This permits immediate updates for some changes = while still not keeping stale information indefinitely. On the other hand, maybe that sort of mode-specific complexity is better = left to the modes themselves?
