Comment (by eschnett):

 Only the default value of the parameter should be changed.

 I am trying this change (only changing the default for apply_dissipation
 from "always" to "never"). For some reason, this breaks the test cases
 {{{
     KerrSchild-rotating-180 (from RotatingSymmetry180)
     KerrSchild-rotating-90 (from RotatingSymmetry90)
 }}}
 which don't set any of McLachlan's dissipation parameters, and which
 should therefore currently not be applying dissipation. The differences
 look significant.

 I don't understand why there are differences in these test cases, and am
 therefore not applying this patch at the moment.
