Such A-to-A adaptors and cables always have been prohibited by the USB spec, but people built them anyway. A common usecase for "illegal" A-A cables i remember was connecting PCIe cards (especially GPUs and mining cards) externally to riser sockets.
I have an external 3,5โ HDD enclosure that needs a male to male USB 3.0 A cable to plug into a PC. Still wondering, why they didnโt use Bโฆ
That's really odd. Why use a host connector when a client connector is intended for the purpose.
Did they entirely miss the purpose of USB?
Cost? A USB-A 3.0 connector is probably a few cents cheaper than a B 3.0 connector
Yeah, it must be that.
I have a similar caddy. Many years old now. The connection to the host computer is a USB-A female, so connecting it requires a male to male cable.
I bought a breadboard power supply and the options to feed it power are a barrel jack and usb-a. Considering the size of the thing mini or micro would have made way more sense.
The ones I have go trough the onboard voltage regulator and you can use them to power USB-devices. I suppose they've skipped diodes and other protective components so it can feed back to the circuit, but I haven't tested that.

In 2001 the directionality became kind of moot. Especially if you want to do attach something with an on-the-go host
An OTG setup needs all 5 pins of the micro-B connector. USB A cannot be used for OTG. If a USB-A port can act as a client, that's not OTG, it's a botched implementation.
Technically, yes... but life finds a way https://pinoutguide.com/PortableDevices/usb_otg_pinout.shtml
