Yep, the only thing I need in a custom Arrive rom is Unlock and Tethering, I believe anything else is just fluff that may in a way break the rom in one way or another. I can do any of the Reg Tweeks I want myself. (BT Audio for Video and max quality mainly).
Unlike roms of the old Windows Mobile days, the stock OS works great out of the box, so messing with things outside of the device (especially one as unique as the CDMA devices now) is not a good idea IMO until things become more standard and tested. Sadly with such little interest in CDMA devices as of yet, we don't have a lot of experience to go off of yet.
(The WiFi issue with the DFT rom is annoying but bypassable. WiFi On, Cellular Data off, Reverse when needed.)
