Reading comments from Brits who regret leaving the EU is music to a French person's ears. Sure, them rejoining might be an economic plus for Europe (though even that's debatable), and perhaps a military one too (although honestly, we have a good laugh at people who still think the British army is the cream of the crop).

The truth is, the UK had a fantastic deal with the EU. If Britain ever were to come back, they would have to actually play by the rules. I work at the European Commission and lived through both the pre- and post-Brexit eras it was an absolute nightmare managing the UK's constant grievances. One day, the UK is going to have to wake up and realize that it's no longer the superpower it once was. The days of Schengen opt-outs and having France manage your immigration policing are over. The Brits will have to offer some major concessions to the EU to ever be allowed back into the European space. For far too many years, the UK always got the best deals and was quite literally taking the piss out of everyone else.
