I guess my first question would be, "what do we hope to accomplish by having GROW adopt this, vs having it remain an individual submission?"
The data are interesting, and while it's no fault of the survey organizers, I'm not sure that 63 respondents is something that I'd consider statistically significant. Additionally, I wish that there were some characterization of the relative size and type of the networks the respondents represent. Since network size and application figures into how much of a scaling/customer impact consideration using/not using/tweaking RFD represents, that's an important point to have. For example, large transit networks may care about RFD as a tradeoff between improved scale/performance and potential customer impact. Small/stub networks care about it from the perspective of how often they or their customers are impacted by upstream dampening. These may lead to widely different conclusions about if and how RFD should be applied. In terms of updates that could be made to the draft: I think that the draft is a bit light on conclusion. Are the survey results meant to be interpreted as support for draft-ymbk-rfd-usable, or simply demonstration that updated guidance is needed, or just as points of data left to the reader to interpret? It would be helpful (if you have the data) to discuss whether the same respondents answered NO or skipped 3.5 as answered NO or skipped 3.6 and 3.7, as that would help to explain the answers as either actively disagreeing with the premise behind "RFD considered usable" or an opinion that does not take that work into account because the respondent was not aware of it.
