It's on our roadmap to support alternate projections, but as you can imagine it's a big project that so far nobody has been willing to pay for to implement unfortunately.
MapLibre GL JS does support globe mode. https://maplibre.org/maplibre-gl-js/docs/examples/display-a-... May we should update our examples to use globe mode when showing examples, especially those that show a world map. We will take that feedback into consideration!
MapLibre's globe mode is both fantastic and performant. Also, it's literally just the one option to change it, and your tile formats/CRS don't need to change either.
It's the easiest way to escape from web mercator projections with no real downsides that I have discovered yet. Also, there is a built-in control if you want to offer a button to toggle between web mercator view, and globe view, since it's all just rendering changes.
