different than any other rim brake?
Stiffer and more aero.

That's not an answer Lou, that is an attribute.
I can't tell by looking at them if they mount
differently or are merely activated differently.
It's a combination of two things.
One is the French randonneur centerpulls with brazed
pivots
from The Olden Days:

Which was, at the time, an actual innovation.
The other is 'the stuff we sold you last year is no good.
Here's the new one'.

I suppose that bracket attaches in the weird manner to
the carbon fork so that they don't have to mold in hard
mounts. That was what was confusing me and that sort of
clears it up. Thanks.
Huh???? For direct mount brakes you need two mold ins.
That bracket is an adapter to attach a normal brake to a
fork for direct mount brakes.
Lou
And that's an adapter for a rather unique brake.

That is a rather unique brake. About as unique as the
Shimano AX:

I enjoy occasionally browsing through _The Data Book_, which
is mostly a collection of drawings of then-new bike
components from the 1920s through the 1960s or so. There are
countless different brake designs illustrated. It goes a
long way toward proving there's nothing much new under the
sun, at least in mechanical bike parts.
Weird is a personal attribution.
I would counter that brazed mounts for a Mafac Raid (a wildly popular
brake at the time) was a logical improvement at negligible upcharge on
an artisan custom frame of the era.
I started avidly bicycling in the era of centerpull brakes - ones with
rather long arms, to give clearance for 1 1/4" tires plus fenders. Those
were very flexible indeed.
As a newbie, I remember seeing in one mail order catalog a touring bike
being sold with centerpull brakes mounted on brazed-on studs, as is done
with cantilever brakes. I'd never heard of such a thing, but I could see
that would make things considerably more rigid.
Eventually, before a re-paint, I brazed mounts onto that old Raleigh's
forks and stays, for Shimano 600 short arm cantilevers. I think these
are probably more rigid than the centerpulls would have been, if mounted
on similar studs. That bike just got back from a heavily loaded grocery
run. The brakes still work fine, decades later.
