If you look at some of the latest carbon offerings you'll see several
examples of "non-racy" position.  Specialized Roubaix  and Trek Domane
immediately come to mind; it's also interesting to note that the short
head tube "racy" Madone is a limited, special order item as well.  The
standard Madone comes with an extended head tube to allow a more upright
position.

I think it's time for us to challenge those who (like the reviewer of
the San Marcos in Bicycle Times) immediately label bikes (especially
such as Rivendells) like this as "retro geometry" or "non-modern
geometry."  It's downright lazy thinking, and if anything, given recent
trends such designs are the latest thing, not something quaintly
antique.

As in fact actually happens.  BQ did a review of the carbon 
Calfee Adventure which they liked quite a lot, especially
http://www.calfeedesign.com/carbon-fiber/model-calfee-adventure/
(includes a link to the BQ review) when fitted with 30mm Cypres tires.
Also, the Seven Axiom (titanium, also recently reviewed in BQ) can be
had with clearance for 28mm tires and is billed by Seven as a bike for
long distances/randonneuring.  (Curiously, although these are recently
having a surge of popularity in my bike club, none have been ordered
with either mounts for fenders or with clearance for 28mm tires.)

The biggest limitation appears to be either the availability of carbon
forks with appropriate clearance, or the mind-set of the manufacturers.
