Comment (by tscrim):

 All `is_RealIntervalField` does is
 {{{#!python
 return isinstance(x, RealIntervalField_class)
 }}}
 So I think a better check would be
 {{{#!python
 if isinstance(x.parent(), (RealIntervalField_class, RealBallField)):
 }}}
 Also, could you make the statement {{{:trac:`20069`::}}} a little more
 verbose? Something like
 {{{
 Check that this works for arb elements (:trac:`20069`)::
 }}}
