The dust I would be concerned about is that which is already on the
sensor before the pinhole is affixed. The greater depth-of-field
will make any bits of grit on the sensor show more obviously, just as
stopping down a regular lens will, and the wider the field of view of
the lens the more it will be noticeable.
Cheers,

Dust should be the least of your problems, really. The area of
that pinhole is orders of magnitude smaller than the slots that
allow connecting the outer control rings on a conventional lens
with the optical innards. Also, many lenses, esp. zooms, act as
veritable suction pumps whenever you zoom or focus. In fact, this
is a worse dust source than changing lenses now and then (in
reasonably clean environments).
