Nah, USB-A should have died a long time ago, and I'm happy that Apple no longer feeds the industry's laziness and inertia.
I, too, have a bunch of USB-A peripherals left, so we're probably in the same boat, but:
- Ultimately Apple's design choice leads me to buying only USB-C devices, which puts more pressure on the industry to switch to USB-C, which is a good thing.
- Small USB-C-to-USB-A adaptors are cheap enough to use the devices I already have.
- I much prefer for my really expensive, once-in-a-decade-investment computer to have future-proof modern ports and to have to use cheap converters to use my outdated USB-A stuff instead, rather than having the outdated ports on my expensive computer and thereby make it less future-proof.
