Exactly. it's for "hardwired" links in programs or RfCs,
where it's impossible to change the URL later.  It's not
meant to be a "pretty URL" or "tiny URL".

Did you say "millions of hits per day for any why.html" ?
IMHO that's far too much.  Why.html is only used for FAIL,
if the domain owner and a mailbox owner in this domain
"disagree" about the set of permitted IPs, or if a stupid
recipient checks SPF behind his MX.

The latter case is quite obvious, I got my first SPF FAIL
bounce after 10 months of testing some days ago:  It was
an obfuscated NetSol whois address redirected to the real
address resulting in a correct SPF FAIL.  I simply sent
it again directly to the next hop, problem solved.

why.html is more interesting when users don't know their
"own" sender policy (defined by the domain owner).  In all
other cases it's unnecessary to ask why.html

a URL like http:/purl.net/spf/ is just one notch above
something like http://spf.myisp.com/.

More like "below", Web directories and crawlers love the
domain part of URLs more than the path.  And it's a worse
<http://purl.net/net/spf> - obviously not meant to be a
"pretty" URL.  With only one "maintainer" at the moment
it's a potential trap, see also

http://purl.net/maint/display.pl.cgi?purl=/NET/spf&id=nobody

That's where I could add more maintainers, who could then
edit the PURL, when why.html is down or moves.

(and we want to play with the big boys, right?)

I'm a bit beyond the age when I wanted to play with the big
boys.  Now I just want to get it right, especially for the
innocent bystanders who have no idea what's going on in the
games of these big boys.
