The ACO has now put that CanAM thing on their website... It's in French, which I got a C in.
I think it says something to the tune of "Could this be one day run at Le Mans?"
In which case, even the ACO doesnt know.
Edit:
"Enfin, si cette édition Can-Am fait clairement référence à un championnat nord-américain organisé entre 1966 et 1974, les aficionados de l’endurance ne peuvent s’empêcher d’y voir une base idéale pour une déclinaison répondant au règlement GTE de l'Automobile Club de l'Ouest.
La dernière participation d’une McLaren aux 24 Heures du Mans remonte à 1998, édition marquant la fin d’une épopée de 4 ans et marquée par une victoire surprise en 1995."
While The Can Am name references the North American championship which they entered from '66 to '74, (This is the sketchy part) Endurance Aficionados cannot (stop) to (see) that this could be a good base for a GTE car in the ACO.
The last time McLaren was in the LM24 was 1998, they got one win in 4 years with a surprise victory in 1995
It's such a word-y article that it's hard to tell what they mean. They are either saying, point-bank that it would be hard to make it conform, or that there is potential for it to be in said class.
Is there anyone actually fluent in french?
