To enforce a heirachial level of oversight is against God's nature. God was against the request for kings in Israel, so no different two millennia ago or now. The use of "Governor" to support a heirachical structure is stretch as nowhere can evidence be found in the bible to support it. If God wanted an organization for a universal church then it would leap out at you from the bible and would be seen early in its origins in Paul's letters, clearly structured in Acts and scriptually supported by the time the Gospels were written, which were amongst the last.
One of the oldest meanings of the word is, interestingly, "Tutor". This would fully harmonize with the rest of the bible where Jesus is spoken of as a teacher, the Law as a tutor leading to Christ, etc. The notion of a governor in a 1st century congregation would be a man or a woman (a governess) who is simply leading a Christ-like life. Being submissive to them did not mean to fall under their authority or control, but rather be humble and compliant to God and Jesus, (NOT humans) by copying their example which would benefit all in association with them, show love for their God and his son and be evidenced by the good they did for one another and their neighbours.
