I guess it would be nice to see that it has been used, so we can then decide if it is safe to delete or not.
But you can always save to and external folder first, then delete and see if anything is missing.
If it is you can bring it back or add it to a linked library.
If you do just delete it and then find it is missing - it is too late (unless you don't save the main file).
