I would presume the usual reason is you want enough hydrogen
to resonate at the desired microwave frequency, but not so much
that you wreck the Q (spread the line width) with excess collisions.

It is worth knowing that active masers have a span for how the hydrogen
in-flux will make it oscillate or not. Too little or too high, and the
oscillation will die off. It may be one of the things to tune up if you
got an older one which needs a bit of good old Love, Tender and Care.
BTW: I always ment to ask, what makes H-Masers stop when there is
too much hydrogen? I can understand too little H causes the system
not having enough atoms to probe (or not getting enough energy into
the system for active masers), but i don't understand the "too many" case.
