It allows you to react graciously to the audience after a performance without an intermittent fumbling and hissing phase. Thats most of it I guess. Some instruments do not even have an air button, and on many it is inconveniently placed. I am actually glad that my main instrument was specially-built for a player used to diatonic instrument air management (where you have to compensate sometimes for serious mismatch between pushing and pulling): an easily reachable decorative stripe running down the whole length of the bass side is an air button with extra-large (and thus rather silent) hole.
That makes bellows adjustments comparatively convenient, inconspicuous and fast.
Another rationale is that the usual starting position is on the draw from a closed bellows (for similar reasons): ending there allows you to start the next piece in a common starting position without an additional setup phase.
I am currently working on one piece starting with two 4-bar segments on one breath each, and a crescendo in between. This only works by starting from an already half-open bellows and it is surprisingly hard/awkward to remember moving to that starting position before even beginning: its just so common to start with a closed instrument.
Finishing a tune on closed bellows is another thing I have never quite understood.
