It's early days, but there is an attempt to standardise how headsets are specified. Codes are very similar to Cane Creek proposed names.

Anyway, for Orange bikes, the technical headset descriptions are:

ZS44/28.6|ZS56/40 - for a tapered MTB fork steerer tube in the 44-55.95zs frame
ZS44/28.6|ZS56/30 - for a straight 1-1/8" fork steerer in the 44-55.95zs frame

The name goes like this upper|lower:
upper: bearing location (EC, ZS, IS), headtube bore (30, 34, 44, 49, 56, etc.) / fork size at stem (25.4, 28.6, 38.1, etc.)
lower: bearing location (EC, ZS, IS), headtube bore (30, 34, 44, 49, 56, etc.) / fork size at crown race (30, 40, etc.)

Bearing location refers to whether the headset is a tradition External Cup (EC) fitting, a Zero Stack (ZS), or an Integrated System (IS).

At first glance it might appear complicated, but it is the minimal amount of info required to define a headset now. All the manufacturers are still free to name headsets as they wish (for example Hope may still use letters and numbers) but they will explain the letters and numbers in the above terms to make fitment info universal.
