It might also be worthwhile to generalize PTVs to work with
sections.  For example:

    {PageName#section$:Date}

would grab the $:Date PTV out of PageName#section.  Then applying
a template to a single section simply becomes a variation of

    (:include <templatepage> basepage=<datapage>:)

except that <datapage> here would be allowed to contain a section
identifier.

FWIW, I've been thinking that parameters to include should be
usable as {$$var} inside the included text, so that the above
could be something like

  (:include Site.BlogTemplate heading="A new entry" author="Jim":)

and we'd just need a convenient way to get multi-line text
values into something that could be used by a template.

Perhaps instead:

  (:include Site.BlogTemplate 
            heading="new entry" author="Jim" text=$:comment1 :)
  (:comment1:
  Some text
  from a textarea input box.
  :)

  (:include Site.BlogTemplate
            heading="reply to you" author="John" text=$:comment2 :)
  (:comment2:
  What is all this about?
  more text lines...
  :)

Inside of Site.BlogTemplate, {$$text} would be replaced
with the value of the "text=" argument above, which would
result in either {*$:comment1} or {*:comment2} and grab
the appropriate PTV.

Just some rambling thoughts.  FWIW, it is _very_ likely that 
(:include:) will end up processing {$$...} variables from the 
arguments to the include directive.
