[TxMt] warning for command key-equivalent conflicts?

[kumar mcmillan]

was wondering if TextMate could throw a warning if the key-equivalent 
you're assigning to a command will wipe out a pre-existing 
key-equivalent.  From what I've observed, if you add a key-equivalent 
[that already exists] to a command then the command works --as 
expected-- in that key-equivalent, silently overriding what was there 
before.  Hopefully not something too difficult?  I guess that would be 
helpful for macros too.
