I am even happier because I can not only identify present blacklist but I
can include domains with excessive ip ranges and blacklist them before they
are used and thus prevent future spamming sources.
Just for clarification spf is designed to reduce spam and spoofed addresses
otherwise it is not needed.

Probably, but this is *still* an improvement over the status quo, when
spammers can use *any* domain with impunity.
I would be perfectly happy to see the spam problem reduced to a few dozen
domains I have to blacklist, instead of the current game where you have to
dig
through headers to try to figure out who *really* sent that mail that says
it's from microsoft.com. (Not to pick on Microsoft -- they're just a
domain
that gets spoofed a lot.)
