Just now, Tramp Graphics said:It is a declaration of variation in superior hilts.
Wrong. Here is the text AGAIN.
While most lightsabers are austere and utilitarian, some Jedi have been known to personalize their weapons to better suit their tastes and styles. Numerous cosmetic or practical enhancements can be applied to a lightsaber, from rare metals and precious gemstones to customized grips and locking activating switches.
Note that other attachments don't ask you to make a giant leap in logic like you are doing. Here is the next attachment in the CRB:
In the days of the Republic, the Jedi allowed their younglings to train with "training sabers,” non-lethal versions of their famous energy blades. A training lightsaber is almost the same as a standard lightsaber; however, the crystal is replaced with a training emitter. The training emitter creates a blade that is completely non-lethal, and at most can generate a stun shock. A training emitter is a lightsaber crystal.
If FFG wanted to say what you are claiming they wanted to say, they would have said it.
