I would suggest the facts that:
  * <ol start="">, at least, is widely used (see e.g. [1] although beware of the 
relatively small sample size - this makes it hard to see use of <li value=""> if 
it is present on < 1% of pages)

* Both <ol start=""> and <li value=""> are well supported in UAs

* When used, they convey important information about the list items - 
information that is not, in general, presentational

are good enough good reasons for including them (indeed I would question why 
HTML4 ever deprecated them). More specific use cases are given in e.g. the top 
of [2].

This rule only applies if there is only inline content in the list item. If 
there are multiple paragraphs, presumably marked up with multiple <p> elements, 
the rule doesn't apply.
