The authoritative sources (geographical institute, statistical office, 
cabinet office, etc.) cannot, by law, publish those datasets with WGS84 
as the sole CRS. The authoritative CRSs (and MUST used ones) depend on 
which part of France we are talking about. For the metropolitan 
territory, this is RGF93. For the over seas islands, it depends again. 
This is not specific to France neither, many other European countries 
have similar rules and bylaws.
