This *is* becoming more popular; in the US, the main problem is that many
(most?) of the exchange points are operated by telcos, who are tariffed.
This means that any connection between separate entities is a "circuit"
that they must charge a certain minimum amount for.  As more telcos manage
to move their exchange point operations into the non-regulated portion of
their respected businesses, this may change, and exchanges are currently
being built by non-telco entities, which are allowed to have more
reasonable charges to connect cages in the same facility together.
(Disclaimer: in my other life, I work for one such facility... the PAIX in
Palo Alto)

Personally, I see this mix of "public" and "private" exchange in the same
facility as being a necessary evolution of the infrastructure of the net;
one size definitely does not fit all.
