Opinions aside, lets look at this.
Low Luck dice.
Germany takes Normandy, South France, Yugoslavia and strafes France. (Leaving 1 French tank and 1 French fighter, retreating to W Germany)
UK does not scramble any fighters to defend Royal Navy.
UK lands 5 fighters, 1 tactical bomber and one bomber on France.
Leaving the following battle:
Italy attacks with: 2 inf, 2 art, 1 arm, 2 fig and 1 bomb
French/UK defends with: 1 arm, 6 fig, 1 tac and 1 bomb
This is a 100% battle in favor of the French.
Italy attacks, French win with 3 British fighters remaining
Even if you get lucky and only leave the French fighter on G1, its still 95% in favor of the French when Italy attacks.
Unless i’m really missing something this move would almost always be a total disaster for the axis.
