Ok, I will remove this method variant from the codebase (I'll need to update a unit test).

Unfortunately this "no `DebugName`, we need to pass the `FullName` issue" also affects the templated overload below this one, and _that one_ is used by a dozen unit tests, so modifying it would be bothersome (I would like to skip updating it, but even if I do it perhaps it should be in a separate commit).
