Renaming extension constructors can definitely be useful. Essentially, it is required
if you want to have an extension constructor as the parameter or result of some
function.
The testsuite contains such an example:
https://github.com/ocaml/ocaml/blob/trunk/testsuite/tests/typing-extensions/msg.ml
In that example, the function is a functor which returns fresh constructors. The name of
this constructor is just `C` since the functor does not know what the constructor
represents, but it can then be renamed to something more suitable.
