Using ZWJ to control ligation is admittedly a new concept, and it mayRemember, though that the Unicode approach is that ZWJ is *not* the preferred Unicode way to support things like a discretionary ct ligature in Latin text.

not have been taken up yet by many vendors, but that seems like a really
poor reason to discourage the Unicode approach.
Proprietary layout features in OT-savvy apps like InDesign might get the
job done, but wouldn't it be better if app vendors and font vendors
would follow the Unicode Standard recommendation? You never know, it
might even reduce the number of requests to encode ligatures.
I know that you and I disagree with to what extent ligation control belongs in plain text, but the standard clearly allows both approaches. The ZWJ mechanism is not *the* Unicode approach.
