Pushpasis -
Not all conflicts are intra-area - so your response does not cover all cases.
In addition, your proposal introduces some new problem areas. Do we leak the
prefix but remove the conflicting SID info or stop leaking the prefix entirely?
If you think about these issues I believe the advantage of Stefano's proposal
becomes clear.
