Honestly, I don't think there is much there to be argued. craigraw provided his views on the repo as an issue. dochex who wrote the spec replied with some feedback.
The main points that can't be bridged are that emended security will favor low dependency and simplicity. On a more personal preference the hard typed parts and using QRs they way they were designed.
I don't want to speak for Craig, but I think his argument for it is more in terms of being pragmatic because it's already deployed. I also think desktop folks have more resource luxury.
There is no buy in from any major vendor aside from sparrow for that BC org, if they really wanted to be a big install base org those would be BIPs
I think the drama the cloners brought over this was more for attention than anything useful. After all these are just QRs, there is bigger fish to fry. A couple specs can even coexist.
