Well, mainly what I did was write up a paper for one of the approved survey items.   The request there was definitely for components.  The request was the spirit of people converting what would have been module variables into components of a type, but still wanting the facilities afforded module variables.   The expectation is that DATA subgroup consider the paper for a particular survey feature.  The various add-ons proposed below are unrelated to the survey feature, and should be a separate proposal, in fairness to the people who supported the survey feature. 

It seems inappropriate for someone to hijack a paper written by someone else and create an r1 converting it into their paper (and in the process nullifying the original).  The original authors or subgroups are the entities that create paper revisions.  I have no plan to create a revision of 18-265.   That’s an issue for Data subgroup at 218.  (The paper is marked “deferred” in the m217 paper list.)

Cheers,
Bill
