 The GeoJSON format has been recently standardized in RFC 7946. In that
 standard, the use of the WGS84 coordinate system is mandatory.

 Quoting [https://tools.ietf.org/html/rfc7946#section-4 RFC 7946]:
 4.  Coordinate Reference System

    The coordinate reference system for all GeoJSON coordinates is a
    geographic coordinate reference system, using the World Geodetic
    System 1984 (WGS 84) [WGS84] datum, with longitude and latitude units
    of decimal degrees.  This is equivalent to the coordinate reference
    system identified by the Open Geospatial Consortium (OGC) URN
    urn:ogc:def:crs:OGC::CRS84.  An OPTIONAL third-position element SHALL
    be the height in meters above or below the WGS 84 reference
    ellipsoid.  In the absence of elevation values, applications
    sensitive to height or depth SHOULD interpret positions as being at
    local ground or sea level.

    Note: the use of alternative coordinate reference systems was
    specified in [GJ2008], but it has been removed from this version of
    the specification because the use of different coordinate reference
    systems -- especially in the manner specified in [GJ2008] -- has
    proven to have interoperability issues.  In general, GeoJSON
    processing software is not expected to have access to coordinate
    reference system databases or to have network access to coordinate
    reference system transformation parameters.  However, where all
    involved parties have a prior arrangement, alternative coordinate
    reference systems can be used without risk of data being

 Therefore, I suggest to won't fix this ticket. Any comment?
