I begin to suspect that people are talking past one another here. Allow
full control to whom, using what? AFAIU (and I may not understand far
enough), OpenType allows control to the font designer, not to the document
author/transcriber. It is the latter for whom ZWL/ZWNL caters.

In cases where it is incorrect to ligate, though the default says to do
so; or it is incorrrect not to ligate, though the default says not to.
A hypothetical example: suppose there are certain words in Arabiform text where
lam followed by alef must appear, but *without* ligation. How would that be
represented in Unicode? Because it is a matter of correctness/legibility,
it is a plain-text distinction.

(There may be no such words, but that doesn't affect my current subpoint.)
