Since Junos 14.1 it has caught up with Cisco, and it has implemented
exponential back-off for interface damping. So you don't have to cause
a static penalty as above, but can penalise actually flapping
interfaces, instead of killing convergence on the first transition.

But indeed doesn't really address what OP is asking, and I don't
think, outside scripting, there is a direct solution to what OP wants.
Clearly any vendor could implement exponential back-off damping to any
protocol which has up and down state, and they could write the code
once, and reuse it for everything, so it's not a tall order at all.
