Arguing against allowing <p> to nest within <p>, and ambivalent about
a line element, but thinking along the lines of a <subp> element;
what I would /like/ to argue for is to allow <p level="2"> to nest
inside <p> (\equiv <p level="1">) but I don't think that the syntax
rules would allow nesting to be permitted/disallowed based on the
actual value of a parameter...

Surely it all depends how the author writes his/her prose; I believe
that an author /could/, with some justification, interrupt a sentence
to present a table, and then continue with the sentence once the
table is complete (I can probably find good scientific texts where
this has been done, if you are not convinced by arguments that
whatever is possible should also be permissible...). If the sentence
can be interrupted, then the para. containing that sentence /must/
be interrupted.
