Comment (by ncohen):
Two details that may help you decide :
1) The current behaviour of the are_mutually_orthogonal_latin_squares is
to check that the latin squares are latin squares, and so changing that
would mean changing the behaviour of the function
{{{
sage: from sage.combinat.designs.latin_squares import
are_mutually_orthogonal_latin_squares
sage: are_mutually_orthogonal_latin_squares([Matrix([[1,1],[1,0]])])
False
}}}
2) All results returned by the constructors of
`mutually_orthogonal_latin_squares` are checked using this function.. If
it does not check whether the latin squares are orthogonal then we need to
make sure that the output of our constructors are actually latin squares
