I accept, and I will be add these details in R=46C. =20

> In case my earlier message wasn't clear, I was asking for the R=46C its=
elf to be padded out with those sorts of details. The reason being, many =
(most) people won't be already familiar with the surrounding discussions =
that have happened previously, or the reasons for the potentially strange=
-seeming design choices made in this R=46C.
Thanks for the suggestion. :)
