I rather enjoy all the people telling you that your use case is invalid because of inferior compromised solutions available.
There are a bunch of people who express a strong preference for a feature, don't invalidate peoples requirements.
Doesn't matter if that feature is something you use personally or not.
What this does indicate is there is demand in the market for a GrapheneOS/CalyxOS phone with a headphone jack. This is why I'm running a Pixel 5a still!
