How many current phones have a headphone jack? When I upgraded from my Pixel 4a to the 6a (both running Graphene OS) I never noticed that the headphone jack was "missing" because I use a Bose bluetooth headset. And when I want to route the audio through my car speakers? Oh... I have a USB-C pigtail splitter which allows for power to be passed through another UBS-C port and connection to the car audio system through a 3.5mm TRS connector.
Seriously: who needs a headphone jack anymore?
