USB-A is legacy and is going away. It's like serial ports and VGA. Get an adapter for single accessories (they're CHEAP, like $5 for two) or get a little travel dock if you need several USB-A ports and only have one or two USB-C. (or go wireless)
Everything is either going wireless (because it can) or USB-C (because of the laundry list of upgrades it provides)
In a few years the only new things I expect to see on the market that are USB-A are the handful of things still trying to get minimal power or charging. Though even charging is going away due to the low power delivery of USB-A.
Right now Woot's got a dual USB-C 35w GaN charger for $7, and a decent USB-C travel dock for $14. If you're still clinging onto USB-A, start your transition now. Just rip off the band-aid and get it over with.
