It's the future, and phones have minimal holes. Wired USB-C headphones do exist, but the solution to storage space has largely trended towards "well have you considered the โ๏ธ cloud โ๏ธ ?"
Frankly I'm just glad USB still exists at all on phones. I suspect eventually that, too, will begin to disappear in favor of "haha well we have wireless charging.... What, connect your phone to a computer? Attach a peripheral? Why would you ever want any of that??"
