What would interest me more is innovation at the airport end of things. Much faster travel links, much faster security. Or are airport perversely incentivised to not do this to sell overpriced food and trinkets?
Thus, there is very little incentive to keep you in the airport less, and multiple incentives to keep you there longer.
Additionally moving security to the gate rather than having a single security point for all flights also makes the wait here shorter and more importantly predictable.
If I'm just taking a cabin bag I always arrive 35-40 minutes before a flight and have had no trouble with time, normally enough time to grab a coffee too before boarding.
