RSART- Redefined operations don't propagate param changes

Problem description
# in base class define an abstract operation
# in derived class rename it
# in base class rename abstract operation
# in derived class observe operation name has changed (may also work
for cut&pastes of redefined)
# in base class change type of the abstract operations parameter
# observe that the type change DOES NOT propagate

Mattias has the following comment on this issue:

"The requested functionality does not exist. The user needs to update
the signatures of redefined operations manually."

    As part of the review process, we strive to be transparent about our intentions with each enhancement suggestion.

    This idea is either outdated or has been implemented in one of the versions. Please check with latest version (V 12.0 at the time of writing)

    The offering team has carefully reviewed this idea and has decided that it does not fit into our current plans, so the idea will be closed. The idea will be kept in IBM's ideas repository and may still be voted on. It might be reassessed or reopened for additional feedback in the future. We value your feedback and thank you for allowing us the privilege of partnering with you in developing our products.

    Unfortunately the UML representation is to duplicate the signature for a redefining operation. So each operation has its own signature representation, even an operation that redefines another operation and hence has exactly the same signature. Perhaps we should implement this RFE in two steps. The first step would be to extend the current way we propagate operation name changes to also cover other changes in the signature, but still limit this propagation to only work for loaded operations. The second step could then be to implement the proper refactoring command that would be able to update the signatures also for unloaded operations. If you agree with this approach we will investigate accordingly.

    We can see the usefulness of this, but we typically load the open models into memory first, prior to doing anything else. The initial problem is that when we do so, we see a change to the base class function name take affect in redefined functions. We do not see the same change in parameters take affect.

    We were hoping that something similar to how TC inheritence was being done- that the efx file on disk would have a link to the parent function, and have nothing else in that efx file aside from things that are overriden within that redefinition.

    For example, looking at a TC file on the disk shows that the copyright field is not anywhere in that file, as it is provided by the parent TC. We could override it, which adds to the file, but for any non-overriden things, any updates to the parent get pushed down to the the child.

    Currently planned for 8.5.1 CP2. We need to add a new refactoring in the Refactor context menu. The propagation cannot be automatic as this would force all models to be loaded (i.e. it would be slow).
