This is not true. You can apply for a redress number to prevent future exception handling. The TSA and DHS makes this an easy process, I have helped more than one person through it.
Until it's the German bureaucrats that ruin your day.
This is an international issue and a national answer doesn't solve it.
For what it's worth my first name is also not accepted correctly (it contains a hyphen) and I never had a problem so far. But every time an airline asks me to put my name exactly as in the passport I cringe.
That aligns with my understanding with how the redress process works. The facial recognition side is getting better, DHS knew who I was and my return flight details returning from overseas today with only taking my photo. No need to present my passport, as my biometrics are linked to my global entry profile (which has a known traveler number you can provide to airlines when booking). I would expect this to be generally available over the next several years.
