A lot of devices don't need what USB-C offers: USB-A is a concurrent, not legacy, standard. You want USB-C for high-power, high-transfer-speed connections. An incredible number of peripherals don't need either of those things, connecting them with USB-C just makes no sense.

"No sense" seems like a strong claim. USB-C is a better plug (reversible, durable). I don't know how much more expensive USB-C might be, but considering the number of cheapo devices that come with an unwanted cable with at least one (often 2) USB-C ends, I assume it's not all that high. The main use I encounter where USB-A is actually better are dongles that don't stick out.

  Can't say the USB-C is all that much of a better plug. Reversible: certainly convenient, but the tiny little stubby easily breakable plug? Strong minus. I've snapped a million micro-USB connectors (may it die as many deaths in favour of either real USB-A or USB=C), more USB-C connectors than I wish I had, but I can't remember ever snapping a USB-A connector.

    Eep, I've had much better luck than you! My bigger concern for tugs would be whether the plug or the socket broke first, I think, though I don't know what fares better by that metric

Usb4 does not define "type-a" connectors, thus type-a by definition is not "concurrent" with type-c in the usb spec. It is deprecated/legacy (ie still in use but not supported by newer versions of the spec)

  That's very much not how USB version numbers works. Each version replaces a previous version "within the same generation", while guaranteeing backward compatibility with USB 2.0 (at least for the foreseeable future, given that it's unlikely that devices that only need USB 2.0 features will ever disappear). - The USB 3.2 standard replaced 3.1/3.0, but explicitly did not replace USB 2.0 - Similarly, USB 4 guarantees USB 3.2 and USB 2.0 compatibility. It doesn't matter that USB 4 does not define a Type A connector for USB 4 connections: a USB 4 controller can accept Type A on circuitry that's designed to operate in USB 2.0 compatibility mode.
