F1 25 Suggestion - Free choice of driver number

If that's the case, then how come that 

1. The 27 wasn't available in F1 22 even though Nico Hulkenberg was just an Icon driver, meaning you needed the Champions Edition to use them? 
2. The 21 is accessible in F1 23 even though there's a chance that players have an old career save with Nyck de Vries in it, who has the 21? 
3. Almost every Drivatar (AI of real players in F1 World) has the same number? If you really think that, then every single driver in F1 World needs different numbers.
4. You can take the numbers of Icon drivers? If you think that, then they must be inaccessible as well. 

See what I mean? These four cases are the very reason why I want the free choice of numbers, and if you happen to play Career mode with the number of a real driver, said driver should be assigned to a different number. It's not that difficult to implement, and I've experimented with that in the past, so it's clearly not impossible. 

Also, it's a video game, and even Frontier allows us to mix up the team lineups and change the race calendar, something we have been screaming at EA SPORTS to implement it, which they never did. I only suggested the free choice of numbers because it's a super minor addition that's not hard to implement.
