If, hypothetically, VGA didn’t have a 5v rail then how would power get from the monitor to the HDMI adapter. It would absolutely have to be a part of the spec.
If the vga/hdmi adapter is active then this abomination could actually pass display information provided you had a micro-usb device that supported display out over usb (idk if there is such a thing and if so it probably doesn’t work all that well but still)
Doesn’t matter. The VGA to HDMI adapter is active, not passive, so it matters if HDMI has a 5v rail, not VGA

It doesn’t need to be 5v. An active adapter can have a buck converter.
In reality active HDMI adapters get powered by the HDMI device though, not the VGA monitor, so it’s a moot point anyways
