In my rules a pass lifts all ko and superko bans, so to stop play there is a three repetition rule, which usually means three consecutive passes. In the first phase of play passes are free. If the players cannot agree about scoring, e.g, about dead stones (which are removed and counted) or one way passes or whatever, or even if either player requests resumption of play, there is an encore that also ends with three repetitions, and passes cost one point (via pass stones). However, if the same player starts and begins the encore, the other player must hand over a prisoner. At the end of the encore all stones on the board are considered to be alive and all empty points surrounded by stones of one player are the territory of that player.

If I understand correctly that means that seki are counted more like area counting than territory counting. That means that your rule lies somewhere between chinese rule and japonese rule, doesn't it?
BTW it seems it is the same in the Lasker-Maas rule.
Aside from one way dame, which rarely occur, the main difference is that territory is counted in seki. That makes my rules and Lasker-Maas rules a form of chilled go for area scoring.

A hybrid between area and territory scoring is Button Go.

See
https://senseis.xmp.net/?ButtonGo You can implement Button Go without a physical token with a simple alteration of AGA rules. Instead of requiring White to make the last pass say that if the last player to pass is the same as the first player to pass, then the last pass is free. And then, if play resumes, if the last player to pass in the resumption is the same as the first player in the resumption, that pass is free.
Edit: In CGT terms 6½ komi may be written {-7|-6}. A play in the komi loses ½ point and is equivalent to taking the button. OC, taking the button gains ½ point in area scoring.
