Thanks! Tracking historical changes is a great idea, but this requires perfect data from day one, doesn't it? Otherwise, how will you differentiate between historic changes and mere factual/technical corrections? Thus, right now, there are no plans to track this. But we're open to ideas and contributions on how to do this. Regarding the reference frame, that's definitely an issue. Right now, it follows the souce's guidelines (see "SOURCE.md"), which means "boundaries of sovereign states according to defacto status. We show who actually controls the situation on the ground. For instance, we show China and Taiwan as two separate states. But we show Palestine as part of Israel."
