Comment (by mmezzarobba):
The way I understand it, what this ticket really does is not to make “the
precision of arb balls” that of their parent, but to round newly created
balls to the precision of their parent by default. IMO this is a
regression compared to the existing implementation (so I'd be in favor of
closing the present ticket as wontfix), but a small one (so I'm not going
to further argue against it, I just won't review it).
Incidentally, I don't see how “`arb` handles precision in a way which is
completely different from anything else in Sage”. For example, you can
have power series truncated at any order in a `PowerSeriesRing` with any
`default_prec`.
