When is the earliest and latest F1 26 DLC will be out

F1 games should always strive to be as realistic as possible, closely resembling real Formula 1. I also don't see what the objections are to intelligent energy management. Furthermore, I think that just before a DLC release, one shouldn't demand something that would drastically alter the gameplay and handling, because it wouldn't be nearly as simple if the development team had focused on the new regulations.
Adapting to new rules and driving styles is commonplace in motorsport and should also be reflected in games about racing series.
Yes, you will go into the curves a bit slower, but in the end you will also be able to take the curves more cleanly, which should be particularly interesting in online races.
Beginners in particular should be able to get closer to the more experienced among us, and this could make the game and online racing more fun for beginners, which would especially benefit online leagues in filling their lobbies even at the end of a season.
But let's wait and see what the developers have done in the DLC; so far we don't know much about it.
