You have a working mechanism.

In the worry that this mechanism might not be properly configured, you
add lots of extra complexity to BGP, which will have to be implemented
and maintained by vendors.  Every new line of code has the risk of 
carrying bugs, so if it's not beneficial (because a working solution
exists) it should not be added.

Otherwise: what Robert says.
