[EM] Anti-defection strategy device for IBIFA

[Michael Ossipoff]

Sure, if full chicken-dilemma prevention could seriously jeopardize the
CWs, making it more difficult to elect hir, requiring more insincere
strategy to elect hir, then that could outweigh the benefit of fully
getting rid of chicken-dilemma.

The chicken-dilemma won't be as common as a CWs. That's one reason why I
don't let the chicken dilemma keep me from proposing ordinary Approval.
Another reason is the Nash equilibrium that Forest mentioned, and the
stronger position of the A voters if they're well-known to probably be more
numerous than the B voters.

The desirability of easily protecting the CWs is the reason why I like
wv-strategy...& why I've been reluctant to give up Plain MMPO.
