I have to agree with the above comments that disagree. Although I can appreciate the thought and concern put into this suggestion, I feel as if it would move the argument to another area of the server. If players could solve it in /warp gov, they should be able to solve it privately / without /warp gov and even without a staff member. However, that is not often the case and sometimes there needs to be a mediator to get involved - which is best coming from a staff member. Realistically, I don't think this would help but I don't think it'd hurt either.
HOWEVER, if granted permission by staff members you could try it out for yourself. I know that there is a rule about letting staff members do their job when it comes to things such as this. But perhaps you could ask permission for a staff member to overlook it and see if you can try it without having them go into the effort of implementing. If it were to not work, then said staff member could get involved and take whatever actions necessary (ban / warn).
