I'm afraid my recollection is quite the opposite -- that the intention of
this recommendation was to break the (still) common habit of using <p> <p>
... to add vertical spacing in a page, rather than prescribe parser
handline rules.

I would actually be really annoyed if a parser decided to discard valid
markup I mean, at least if it's still there (with no vertical size) I can
fiddle with it (edit the text, modify formatting, look at attributes.
etc.) but if you've actually discarded it from the parse tree, then it's
gone forever.....

Moreover, doing so would be impossible for XHTML handled by an XML parser,
which simply cannot discard elements on a whim.
