We already have the following text[1]:

> If it is able, the UA may apply letter-spacing to cursive scripts by translating the total spacing distributed to a run of such letters into some form of cursive elongation for that run. Otherwise, if the UA cannot expand text from a cursive script without breaking its cursive connections, it must notapply spacing between any pair of that script's letters at all.

Is this good enough, or do you have any suggested changes?
