This is actually something I had once considered too. It’s not that they want to downgrade the port itself, it’s also that they want to downgrade the AMOUNT of it. I went looking for phones with two ports (I was also curious about using a phone as a data bus) and I could literally find none.
This is why when it comes time to decide on a compromise, Bluetooth (and its audio issues) wins out versus anything with ports. Because it’s a solution that doesn’t throw away options with it.
