Dampening reduces negative effects, but there's still a potential for

CPU resources which in case of OFRV software can easily cause timer expiration
on BGP sessions of peers border routers.

I do not think that deliberately breaking things just to attract attention
of the management is a good idea.  If some vendor ignores bug reports, go
to a different vendor :)
