It is rightly disabled: the primitive exists, but it does not actually
work. I'll add a tracker item. Letterspacing was disabled a long time
ago during the font backend rewrite, and I forgot to restore the
feature afterwards. By now, it takes some work as the code has deviated
quite a bit from the original in pdftex.

Best wishes,
