Not having support for GeometryCollection in MapBox has caused me some headaches.
It's a standard part of GeoJSON, and as such, should be supported. Worth noting is that the GeoJSON standard does state that GeometryCollections should NOT be nested....so support of a single level of GeometryCollection should be a reasonable thing to implement. See: https://tools.ietf.org/html/rfc7946#section-3.1.8
