Comment:
This will also improve the trace in the important case where the field is
the base field.
I think I would call self.base_ring() instead of
self.parent().base_field()
I wonder if this can be further improved. For example if base equals
self.parent() the returning 1x1 matrix should be instantaneous (although
this is a very corner case).
Also, you need to add a doctest for the change.
