None.  But if they *do* want to look like part of the Internet, they should
do so, instead of whining about how Internet sites "must" support pathalias
and the .UUCP hack.

Email, or telephone.  Or even having an account on your DNS server's
machine so you can make the updates yourself.  Who do you think will be
more responsive, your (single) DNS site, or the map coordinators *and*
everyone everywhere who uses the maps?

And pretty soon you notice that EVERYONE is failing to get you mail, so
someone called your Zone Contact and told them to fix the zone.  If only
30% of the UUCP map people can't get you mail, you may never notice.

Who said MX records "must" apply to UUCP sites?  They can sit out there in
the maps, and maybe I can get mail to them.  They can get in the DNS and
improve their chances.  It's up to them.

The root name servers are not "about anyone".

And *they* keep the maps and path files.  At least until *they* get tired
of doing it, and find another "smarthost".  Who gets sick of routing, and...

Every site that *does routing* with the UUCP maps has to keep them around.
With the DNS, sites can do routing without keeping the entire DNS on their
local disk (or even local net).

 JS> To do that reliably requires one MX record for every UUCP site.

It does?  You've never heard of wildcard MX records, I see.

 JS> Passing mail to a gateway requires knowing one address.

Until that gateway changes, goes away, gets out of sync with the maps...

 JS> The latter sure seems to be much simpler than trying to get every UUCP

The UUCP maps are not a "voluntary database"?

 JS> It is, however, less simple that expecting them to.

I don't expect every UUCP site in the world to be in the DNS.  I do expect
those that want to be more reachable from Internet sites to do so.
