It isn't. It's one of the properties that gets assigned to glyphs so 
individual glyphs can be told either or not to kern, make ligatures, 
protrude, expand, tweak dimensions, etc.

There is some more new glyph juggling, like

     \def\UnKernedTeX{T{\glyph xoffset -.2ex yoffset -.4ex `E}{\glyph 
xoffset -.4ex options "C0 `X}}

     \dorecurse{100}{ x \UnKernedTeX}

as well as some scaling features. All to be applied and integrated in 
due time.

> By the way, the ligature suppression mechanism via \startexceptions is already implemented, correct? If yes, it should now be possible to convert the existing wordlists to the new format, right?

Maybe, but not (yet) on the agenda. My priority is now with some font 
stuff.
