Right, as this is more a question of data visualisation rather than editing using the API, I brought up Overpass API here.

I would discourage unconstrained relation resolution for the API, in particular for use cases like the one mentioned here. Looking at the relation 60189 (Russia) with all its nested multi level subareas, this would quickly produce 584MB worth of data. That's a pretty good way to kill your browser.

Limiting resolution to some given level seems a bit arbitrary to me, as it would for sure also depend on tags on the relation or relation member. That's a good way to introduce lots of special logic that is changing all the time.
