Regarding @lrettig's earlier statement regarding non-technical aspects of ProgPoW, and even this difficulty bomb discussion:
This (plus Eth Magicians) is the right forum for discussing the technical aspects of ProgPoW but probably not the non-technical aspects (e.g., “favoring” one class of miners over another). We don’t have an established forum for the latter, but we could set up an EIP0 forum.
I agree with this strongly, and interpret it as: core devs and the various Rings should primarily focus on technical considerations. Legal / philosophical /ethical / political considerations are for a different forum. One needs to be created where it can productively be worked out. The EIP0 group was a good start, particularly w/ subjects around "meta EIPs".
