Jonas, all,:
So I do want to ask a couple further clarifying questions on this point, but I got rather majorly sidetracked :)
I wonder can you (and other list readers!) take a look at my attempt here to summarize what is described in Footnote 2 of the draft BIP (as it's related to this discussion and also .. it's pretty interesting generally!):

(btw github gists have equation rendering now which is nice!)
Thanks,
