You're quite right - removing the stencil would be better
for the tempo changes which implement the fermata.

To explain the padding: the first metronome mark shown here
and some later ones (in other tempi variables) are meant to
be printed.  These set the tempi of the sections of the
piece.  The increased padding prevents collisions with
dynamic marks which often occur at the same time.
