That might be less daunting if there were assembly instructions. I.e.,
I'm suggesting that the instructions need revision. Work there could
have a significant payoff in a larger test community (I'm not exactly a
hardware noob, but I found it annoyingly obfuscated).

That is useful for picking from among the currently supported versions,
but perhaps it'd be useful to take a colleague with you to a store and
see how helpful that all is. It's nearly impossible to find any of the
devices in the list or to verify whether a particular device in a box
has the required version of motherboard and firmware needed.

That turns up quite a bit of devices that aren't supported, FWIW.

Indeed; more isn't better.

May I also suggest moving to another standard that hasn't been
explicitly "end-of-life'd" by the manufacturer.

Sure - I spent several days in Target, Best Buy, and Fry's trying to
decipher whether particular products were supported - again often
difficult without UPC numbers (boxes don't always indicate version)

Here's a good example of how useful the information on the OpenWRT
website can be. Everyone seems to refer to this as "Archer C7", everyone
except the TP-Link website. Their search finds no products matching that
description, and the WIFI routers there are listed with other codes,
e.g.:TL-WDR7500 - except you won't find that number on the hardware page
-- you have to click through to the page for that device.

For that device, like for many, the most recent version (i.e., the one
more likely to arrive on a blind web order, or on most store shelves) is
not yet supported.

Well, the 23-Apr-2015 build by Kaloz works fine - except that the SQM
package fails to install.

What I'm baffled by here is that the main trunk builds leave LUCI out;
that's seems
quite short-sighted, IMO.

And I appreciate and understand that. The CeroWRT site could similarly
use an update.

I.e., there's ample opportunity here to build a larger community with a
few simple steps:

	- refer to routers by the manufacturer's designation
	- create builds with both LUCI and (if possible) SQM
	- make a short-list of a few currently available routers
	for which an integrated build exists *for the most recent
	motherboard version*

All of this could be done on the CeroWRT site until it can be put on
OpenWRT.

These are fairly direct ways to lower the bar, which seems unnecessarily
high here.
