I looked at the Emonda pages. Looks like they are not compatible with standard center bolt type brakes (side pull / dual pivot / etc).
Right now it's a smaller number of frames but I think that we'll see a larger number of them in the future.
It's like threadless fork/stem set ups - when they were first introduced everyone was saying "well it's not worth it" to get rid of quill stems. That design also had duplicated efforts with the quill inside the steerer and long bolts holding stuff together. Now quills are quaint antiquated things that seem inefficient compared to the very simple "clamp the steerer with a few short bolts" threadless stem system.
Likewise BB/crank interfaces have gotten rid of the heavy solid steel BB axle, the two big bolts (typically steel) holding the arms to said axle, etc. With the newer stuff (I have a set of FSA cranks as well as Cannondale SI sets) it's one bolt that's smaller/lighter or even no steel anything except maybe bearings (BB30).
