It's the same at the doctor's or dentist's. Every time I got they hand me a paper form and ask me to fill it out even though they already have my info. They could just ask "has anything changed" but nope. They could also do it all online before I get there but nope. If they're required to file they could print out the info and just ask me to verify then sign it but nope.
The experience is similar, but the consequence of missing a change in health status is potentially much more significant, so I don't think it's quite the right comparison.
As for the phone tree, FAAMG is no better
