The last year standardized version of GeoJSON, IETF RFC7946, mentions in https://tools.ietf.org/html/rfc7946#page-12 """ The coordinate reference system for all GeoJSON coordinates is a geographic coordinate reference system, using the World Geodetic System 1984 (WGS 84) [...] Note: the use of alternative coordinate reference systems was specified in [GJ2008], but it has been removed from this version of the specification [...] """ Regarding OGR, it will support reading & writing GeoJSON files with any CRS. Unless that on the write side you specify RFC7946=YES as layer creation option, in which case automatic reprojection to WGS84 is done.
