It is my understanding that the Dev roms will not get OTA updates as these are not official. I believe the French rom is an official unbranded rom so it should get OTA updates. Now, I'm not 100% sure about this though. But the way I see it, if you're willing to flash to get the GDR2/Amber update, why wouldn't you be willing to flash to get the GDR3/Bittersweet Shimmer update??
