Comment (by cyberpunks):

 Attempt at fixing this in branch rust-protoverlap1 at
 https://gitgud.io/onionk/tor.git

 Writing that, it also seems like leaving version zero as a reserved value
 is useful for protover implementations like this, since 0 is the initial
 value of `last_high` as a placeholder for 'no version seen yet.'
