>I guess I need to buy yet more dongles, or throw them away and replace everything with USB-C peripherals because some 20yo on HN says that USB-A is legacy.
The concern about dongles is so overblown. Let's take your examples each in turn.
>Suppose I have a nice USB-A optical mouse
You buy a USB-C to USB-A adapter and it lives on the mouse's USB-A connector, never being taken off, forever. And then... it's one piece. Are you taking the mouse with you? The dongle comes with it. You don't gotta think about it.
>mechanical keyboard
Same deal. Lots of keyboards even have USB-A ports on them -- which means you only need 1 dongle. One for the keyboard. That lives on the end of the USB-A connector. You have now converted your legacy USB-A device to USB-C and can forget about it forever, for the cost of $5 from Monoprice.
>a really nice $200 audio interface
If you really, for some reason just cannot stand to add a $5 add-on piece to get the latest gear from Apple, many of these devices have detactable cables. So, you can just.. buy a different cable. Let's take the Focusrite Scarlett 2i2, which matches your use case at $200. A replacement cable from MonoPrice is... $5.29. And you can put away the old cable and just... have this one.
At the very, very worst case, you're talking about a $1200 machine and an additional cash outlay of approximately $15. For adapters which attach to the thing you want to use, forever, and don't have to be thought of again.
And somehow this is a travesty against the user? Worth of a scrap-and-redesign of the $1200+ machine?
Or get one of the tiny USB C hubs with four USB A ports on them. A hub like I have now anyways, for an iMac that still has USB A ports, because I needed to plug in more shit.
