Drivers should remember greatest electionId seen, and disbelieve primaries with electionIds that aren't greater.
electionId (in isMaster response) will be backported to 2.6.x.
Justification: only one election per 30 secs, servers must have clocks synced within 30 sec and run 3.0+ (or the 2.6.x mongod with the backport) for read-your-writes consistency with w: "majority" and primary reads.
Set false primaries to state "Unknown", will be re-checked by next periodic monitoring
Justification: will step down and roll back soon, remains a primary with obsolete electionId until then
