Hi Bruno,

On my side, I’d propose

​Do you really think it is safe to propagate ​information which can
completely overwrite Best Path without applying it locally ?

If we are really to change this text how about this:

NEW: The use of Cost Communities MUST be disabled by default. The
propagation may occur by default only on those BGP speakers which do not
set next hop self.

​Cheers,
R.
