I don't really see why... you could also just filter out the /32's if you
needed to redistribute connected routes for some other reason (like if you
have statically assigned PPPoE IPs that aren't in the main pool), which is
what I do (although I distribute the PPPoE IPs via iBGP instead of OSPF,
but I imagine pretty much the same configuration would apply).
