So, it definitely works, in that it stops a low(er) ranking flapping
process from continuing to make new proposals, so then the cycle of
flapping stops. Whenever an up/down state changes and a new/different
proposal is made, then things immediately resume, yay.
However, there's still a problem of the chain state at this time,
I believe. Here's a session that's damped by the flap counter:
SET always_last_partitions ON ... we should see convergence to correct chains.

So, the state of the chains at 21:23:11.221, three seconds after
the flapping detector finished, is:
epoch=484, UPI=[a,d], repair=[c], nodes_up=[a,c,d]
epoch=485, UPI=[a], repair=[b,d,c], nodes_up=[a,b,c,d]
epoch=486, UPI=[b], repair=[c,d], nodes_up=[b,c,d]
The UPIs are overlapping, derp, that won't work, thanks to the magic
of epoch version # enforcement, However, the clients need to concern
themselves with the repairing members, also. As soon as a client
in the epoch=486 sends an op to FLU c or FLU d, those nodes will
wedge themselves because they're in a different epoch. Everyone
will get stuck, and then life sucks.
Future work TBD!
So, this is an interesting case where an asymmetric network parittion
can cause the current algorithm to cycle for several seconds, then one
participant X becomes less active (I'm not sure why), the other two
participants slowly come to an agreement, then X seems to wake up and
return everyone to the cycle/flapping loop.
SET always_last_partitions ON ... we should see convergence to correct chains.

This is a return to the old, possibly asymmetric/unidirectional network
