Problem: Mapframe uses the Cartesian coordinate system, which works well across most of the globe. However it breaks down at the poles, displaying a lot of whitespace and massively distorting the lowest/highest latitudes. For a live example, see commons:Category:South Pole Telescope
Proposed solution: Re-render maps that are close to the pole (say, anything above or below 80° in latitude) by rotating them to the equator before displaying them
Who would benefit: Users/editors working on topics that are close to the north or south pole
More comments: I proposed and withdrew this in the 2019 survey. At the time I was thinking of different projections, but a simple rotation avoids this. There is still the issue that editing the map on OSM at the poles is difficult, though.
