Well, those PCB's look handsoldered(correct me if I'm wrong), so maybe it's even lesser work to just ship the unsoldered PCB's, for guys who have no problem with smd/smt soldering(I think smt soldering ist not much more difficult then normal soldering, if at all).
I know there are many smt projects out there in the web(I did myself a few SMD PCBs).
It's just the idea of DIY gets lost with nothing to do but finding a right case for the module(but thats just my opinion)...
And it's always nice to see how the electronic you build up is working(for the schematic part)
The code is annother section, because there is much brain work in it and it is easy copyable, I understand why you don't want to offer it( if I remember right there were even cases, where the code was copied for commercial projects)
I think the new ARM version will sooner or later replace the Atmega version, because of more (hardware) possibilities, and maybe also the speed(I don't know the current speed resources, because I don't know the code), and just the fact, that you have to develop for two different hardware versions.
But also here: correct me if I'm wrong with my thoughts.
Between I think soldering(also smt) and drumming is combineable
