Comment (by jdemeyer):

 For `Rational` in #18304, a similar argument holds: the only coercion to
 `QQ` from a Sage `Parent` is from `ZZ`. Since you're not using the
 coercion framework for this comparison between `Integer` and `Rational`,
 you're safe.

 In other words: both work for very specific reasons, they are not examples
 to follow.
