I don't think so because you have to construct a strange
topology to achieve the first described effect (persistent
loops); and the second effect ("incorrect" route computations)
is pretty much what can be a desired behaviour. The definition
of iBGP mesh's behaviour as ideal is questionable in many cases.
So, yes, route reflector can behave differently but that can
actually be a plus. As long as you know what you're doing.

PS. Actually, even #1 is not a drawback. There's a lot of ways
to create persistent loops with creative usage of iBGP mesh
alone. That only shows that the tool is powerful enough :)
All in all, the draft is a good piece on less than
obvious dangers of fancy routing techniques.
