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 KT-RPWF (RTL8188CUS chipset) adapter working with a Raspberry Pi 2.

The RaLink Technology RT5370 chipset works, except that it does not provide an available AP list when in AP mode. You can still enter an SSID manually.

I don't want to download the OS image. Can I just install the package to my Raspbian instance?

Yes
