Yes, but that's a slightly different tangent.  If the underlay is unstable,
I think we're all in agremeent that higher layers should not send packets
there.

The interesting question is "how to react when underlay seems to be stable
again"?  "bring up upper layers right away, with exponential decay flap
dampening" or "always wait 15 minutes to be SURE it's stable!!!"...

I go for flap dampening and taking ports into service quickly ("one of the
trainees might be on a rampage, killing the other uplink right next")  ;-)
