We use https://github.com/leaflet-extras/leaflet-providers to run the selection of the various map layers, so the easiest pathway for us to add "new" Mapbox tile support would be to get it added to leaflet-providers...

I assume completely switching to the new style would be a no-go since it would break the currently-working styles, but perhaps there could be a separate "mapbox style" option.

This got done back in 2020 and was released in version 3.2.
