 The point is that if this ticket gets merged but not the follow-up
 (because you might stop doing Sage development or anything) we will end up
 with these two very strange lines.

 Could you at least start with a comment
 {{{
 +            # # we should deprecate this because XYZ.
 +            #from sage.misc.superseded import deprecation
 +            #deprecation(XXXXX, 'passing -1 as PARI variable is
 deprecated, use None
 }}}

 Right. Doctest are indeed important! What is your long term goal with
 those methods?

 `pari_catch_sig_on` and co?
 > See `src/sage/libs/pari/pari_err.pxi`. But `pari_catch_sig_on()` and
 `pari_catch_sig_off` are just `sig_on()` and `sig_off`. This used to be
 different before we had #14894.

 Just for precision: is `pari_catch_sig_on` just an equivalent to `sig_on`?
 If so I really do not understand why there is so much `pari_catch_sig_on`
 without any `pari_catch_sig_off`!

 > Most of your comments are indeed good comments, but my first priority
 was to get the general framework (i.e. this ticket) reviewed, we can still
 improve things later. I prefer to split tickets in smaller pieces, I
 dislike these huge tickets which do everything.

 But I, as a reviewer, do not have your vision of the larger project. I
 just see one ticket (actually there is also the part 2 #17860).
