I don't want to make the vast majority of older *content*
"be considered conforming". I do think it's reasonable to expect
that previous older content which both *works* and *was conforming*
to *continue to be conforming*.

Put another way:
I think it's reasonable to make things that were previously
non-conforming ONLY if they didn't actually work, weren't 
weren't actually deployed, weren't actually implemented.

Extended DOCTYPES and head/@profile are examples of content
that is, in HTML5, non-conforming, but
  * WERE conforming to previously issued specs
  * actually work with current browsers
  * have been deployed
  * have actually been implemented.

The only things obsoleted with HTML 4 were things that didn't
meet these criteria.
