Why just the Raspberry Pi 3?

Wifi Hardware support for 'Access Point Mode' is iffy. It just so happens that the 802.11 chip in the Pi 3 supports it fairly well. Many USB adapters off-the-rack don't.

Will it work with my USB Ethernet Adapter on a different kind of Raspberry Pi?

Since the software is dependent on the Wifi adapter, the answer is "it depends". At a minimum, it must include "AP" in the list of "Supported interface modes" returned by:

sudo iw list

I've gotten the KOOTEK adapter working with a Raspberry Pi 2.
