Comment (by nthiery):

 On the benchmark from #11900, I get significantly the same timing with
 develop and #10963+#15801:
 {{{
 sage: E = J0(46).endomorphism_ring()
 sage: %time g = E.gens()
 CPU times: user 3.63 s, sys: 94.9 ms, total: 3.73 s
 Wall time: 3.86 s       (3.90s for develop)
 }}}
 This, despite the additional full category initialization.
