It doesn't have to actually be right 100% of the time. The balance of downsides and upsides of any chosen solution just have to be more palatable than those of whatever alternate implementation you're considering, with a tradeoff between 100% correctness and ability to be implemented before the heat death of the universe being one of the axes to be considered, as well as the level of benefit provided over your whole user base.

In this case, dropping the extra control/ignoring power users is probably saving a lot of non-power users from shooting themselves in the foot in the vast majority of cases. Pilots (should be) 100% power users. The average operator of a browser is somewhere on the opposite end of the spectrum.

Any real system will have things go horribly wrong for some subset of users on a regular basis. It's impossible to be all things for all people for all situations, so you have to choose your battles.

You mean the 737Max?

Yes, that was stupid. Edit now, thank you.
