This is very true. I also had bad experiences with flight connections in Paris. This was not related to airfrance but to luggage service at CDG.
When I travel with my bike, I try to book direct flight or with limited connection if no direct exist. It also safer to take a longer connection to ensure the bike follows you. When doing connections in Europe I would avoid Paris as much as possible as I had bad experiences multiple times.
However, I travel frequently to Paris for work with my bike. With a direct flight to Paris, I never had any issue.
