Comment (by SimonKing):
OK, these have not been all tests from #11900. Here is another one.
Without full init:
{{{
sage: %time for E in cremona_curves([11..100]): S =
E.integral_points(both_signs=False)
CPU times: user 21.00 s, sys: 0.07 s, total: 21.08 s
Wall time: 21.11 s
}}}
With full init it becomes 21.34 s.
But that's WAAAAAY slower than the time stated in #11900.
So, we have a regression, but it seems we wouldn't make things worse by a
full category initialisation of matrix spaces.
