I remember that there was discussion about invalidating plans who's estimated cost turn out to be severely off when executed.

That's something we might think about after the infrastructure is in
place.  But the question to answer is why the re-plan won't yield
just the same plan as before.

Yeah, also invalidating plans like this only really makes sense once we have the ability to keep multiple plans around for different sets of parameters. Otherwise we could also end up in a situation where after every execution we determine that a re-plan is necessary because the parameters used differ in distribution.
