Relax requirement for `GeoJsonMultiPoint` construction allowing creation using a single point

I stumbled upon a limitation in GeoJsonMultipoint which I find unnecessary - it requires to have at least 2 points. While there are no requirements in GeoJson RFC for MultiPoint to have this and Mongo itself works just fine with 1 point in the coordinates list

Was there a reason to implement it like this? Will it cause backward compatibility issues if this requirement is relaxed?
