Is there any way to automatically validate system triggers to see if I have broken any by renaming columns in foreign keys?

It upset me to discover whilst investigating a bug today the following statement in the docs, which I was not aware of previously:

RENAME column-name TO new-column-name:

Change the name of the column to the new-column-name. Note that any applications using the old column name will need to be modified, as necessary. After the renaming operation succeeds, foreign keys with ON UPDATE or ON DELETE actions must be dropped and re-created, as the system-created triggers used to implement these actions will continue to refer to the old name.

Hopefully I haven't done this in too many places, but hunting through every system trigger doesn't fill me with excitement ...

As a sidenote - why does it not just prevent you from renaming columns in foreign keys as it does with primary keys?

EDIT: This is using 11.0.1.2352. It definitely doesn't seem to be correcting the system triggers automatically on rename!

EDIT to provide an example as requested:

Create a DB (using Sybase Central wizard defaults):

CREATE TABLE A (
     AID                      integer NOT NULL DEFAULT autoincrement
    ,AName                    text NULL
    ,PRIMARY KEY (AID)
)
go

CREATE TABLE B (
     BID            integer NOT NULL DEFAULT autoincrement
    ,BName          text NULL
    ,PRIMARY KEY (BID)
)
go

CREATE TABLE C (
     CID            integer NOT NULL DEFAULT autoincrement
    ,A              integer NOT NULL
    ,B              integer NOT NULL
    ,PRIMARY KEY (CID)
    ,FOREIGN KEY Foo (A)
         REFERENCES A (AID)
         ON UPDATE CASCADE 
         ON DELETE CASCADE
    ,FOREIGN KEY Bar (B)
         REFERENCES B (BID)
         ON UPDATE CASCADE 
         ON DELETE CASCADE
)
go

Then run the following SQL statement:

ALTER TABLE C
RENAME A TO ARenamed;

Oddly, what then appears to happen is that the update columns system trigger is deleted. The delete trigger remains but with the wrong key name (as the docs suggest should happen). This is with 11.0.1.2427.
