Audio 6.5 mm is as close as humanity got to a perfect connector. Unfortunately downsizing it to 3.5 mm removes the robustness of the female as it tends to eventually break

Here's a lifehack that will extend the life of the socket by ~1000x: you can buy a 3.5mm-to-3.5mm "adapter" that you keep plugged in to the female end. Now you have a wear part that is trivially replaceable.
Of course that doesn't work all that well for laptops where it would stick out and easily break when you put it in a bag, but for that one pair of headphones you like that is no longer being manufactured it's great!
This is actually really smart!
There's no "perfect" connector because there are many needs and some conflict with each other.
trrrs is a wild thing to want as the universal connector... They are bad for any actively powered connection since the tip/rings hit EVERYTHING on the way out and shorting. Split keyboard users know that pain.
There is no perfect connector. But a common, standardized connector across applications and manufacturers, which is available now, and has most of the useful features is the next best thing.
