I have seen that the request to independently disabling conditional moves and analysis was rejected and I understand that, as conditional moves could be used to analyse the board even if analysis itself was disabled.
But I believe a better approach is to at least enable conditional moves with depth 1, meaning you can not program 2 sequenced conditional moves when analysis is disabled (you can however plan as many conditional moves as you want that are not sequenced). This limited conditional moves feature can not be used for analysis and would make correspondence games faster and nicer (I doubt anyone needs to use tools to analyse 1 move into the future…)
