Accodring to USB specification A-A male leads are illegal, none of theses cables comply with USB spec.
Nobody will stop them from making it, but this is a violation of USB Spec chapter 6
https://www.usb.org/developers/docs/usb_20_052510.zip

Also you cen read simplified here:
Universal Serial Bus - Wikipedia, the free encyclopedia
USB Connector Guide at Cables To Go

Just imagine someone will use this cable to conenct two host PCs
he will parallel two 5V power supplies - ouch

In contrast, A-Male - A-Female cables are legal and widely used as an extension for USB dongles and thumb drives.

Actually USB spec uses word "Prohibited"

6.4.4 Prohibited Cable Assemblies:
...
• Cable assembly that violates USB topology rules: A cable assembly with both ends terminated in either Series “A” plugs or Series “B” receptacles.
