Why aren't ISPs providing stratum 1 NTP service?

Currently I, and the company I work for, don't mind providing some services
to the "public" Internet community. The company almost always gets more out
of it than it costs to supply. I just don't want to get trapped into
"supporting" public services. I get enough hate mail now when one of
our no charge services goes out of service on occasion.
A related, but more on topic for NANOG, issue is aligning more network
services with network topology. I don't think putting a NTP stratum 1
server on the NAP network fabric is a good idea. I do think providers
exchanging NTP across the NAP fabric is a good idea. Redundant voting
catches a bunch of dumb errors.
A packet saved, is a packet you don't have to carry. Its not as huge
a problem as multiple MBONE tunnels transiting the same physical lines.
But I'd rather have multiple associations at the edge of my network, and
pass NTP in a structured manner around inside my network. The same thing
is true for several other network services.
