   > It makes sense to me that after the resign state the replica should always 
increase its epoch. The replica resigned from leadership at epoch X so 
eventually the epoch will be at least X + 1. Did you consider transitioning to 
candidate and relaxing the transition functions to allow both resigned and 
prospective to transition to candidate?
   
   yes, I decided not to list that as an option because I felt it was equal to 
if not worse than the option of having resigned transition to prospective in 
epoch X + 1. personally I felt it was nicer to have less edge cases to the 
invariant that only prospective should transition to candidate
