In theory, yes. In practice, how does that work? Suppose I prepend
250 times, and a few hops away, routers start to explode because they
hit 255 or 256 ASes in the path? How do these people debug the issue?
Once they know the problem, how do they install a temporary fix as
they wait for a real fix?
why do you assume someone else will care if you lose connectivity
because you've done something obviously pointless?
Small prepends can influence traffic engineering. Large prepends won't
make any more difference. Gigantic prepends cause operators to roll
their eyes, if they bother to look for this sort of thing - which they
rarely do.
If people want to shoot themselves in the foot, then they should be
given plenty of leeway to do so. There's no reason to draw a line at
the ietf for this sort of thing.
