Am I wrong or is the correct substitution for non-commutatives the same as

Whether you enforce integer power subs for commutatives is another issue.
You (apparently) should definitely not be doing algebraic (non-integer) subs
for noncommutatives, so I just add

Whether the current behaviour is correct or not is really unrelated to
commutativity. There are commutative objects for which it's wrong (e.g.
polynomials) and noncommutative on
