I would say this the other way around, all exchange point blocks
should be transited by someone.

Back in the day, things like the mae-east FDDI were originated by
a half dozen AS's.  Why?  If you had "full routes", but didn't
connect to the mae, you could traceroute but not ping it, and things
of that nature.  It confused people.  Of course, the inconsistent
announcements were also an issue.

The right thing is for each exchange point to be announced by one
AS.  I'm not sure if I favor having one AS per exchange, or one AS
for all exchanges, but the point is the same.  The AS should announce
the route.  The AS should get transit (possibly over the exchange)
from one or more players.  The exchange operator should run the box
"announcing" the exchange.
