I think there are two considerations here:
First, France has gone on its highest state of terror alert (vigipirate rouge). This has been used at Terminal I (i.e. not the one Air France uses) to strictly enforce the one carry-on limit. This is not the individual airlines but rather the airport security that does this. I haven't travelled through Terminal II, under these circumstances but it must be similar... This, however, only applies to the number of pieces, they do not weigh them.
Second, in my experience what matters more than any airline policy is simply the nature of the gate agent that you are fortunate or unfortunate enough to be dealing with...
Good luck !
