well, to break it back it suffices to rem
This is all very helpful. Hopefully I'll not miss if there is a beta or rc
version of Sage implementing this - if I fix this with the script now, I
won't be able to test "vanilla"-ish Sage.

No idea why, please open a trac ticket on this.

Indeed the determinant code in matrix2.pyx is a huge mess. Some
dispatch is unavoidable but many specialized matrix implement
their own determinant function:
matrix_complex_ball_dense.pyx
matrix_double_dense.pyx
matrix_gap.pyx
matrix_integer_dense.pyx
matrix_mod2_dense.pyx
matrix_modn_sparse.pyx
I think the problem is that it computes the characteristic polynomial and
then takes the constant term. That seems a bit wasteful, no?
c = self.charpoly(var, algorithm="df")[0]
