I don’t think that the rule can be legally enforced. As it’s a posture taken by French authorities, the enforcability does not really matter.
The question about French being allowed at all at large airports has been raised, as mandated by European regulation. Of course the answer is or will be that French will continue to be allowed.
In your country, is there a “guide VFR” or equivalent?
There was one in the UK, has it been kept up to date?
The French VFR Guide is the package comprising of the 1:1M SIA charts and the accompanying handbook listing the various rules, the D R and P areas and their activity times, yes? I used to buy that pack from the SIA shop.

Probably this.
But it was a pure accident I came across it; I have never heard of it before or since.
