That is absolutely true. I have never argued that the only way to
turn ligatures on or off is in plain text. I saw that there were
difficult edge cases and sought blessing for the ZWJ/ZWNJ mechanism
to handle them, and won the day. But it would certainly be my view
that those should only be used where predictable ligation does not
occur. A Runic font which had an AAT/OpenType/Graphite ligatures-on
mechanism would, in my view, be inappropriate, because ligation is
unusual in Runic, never the norm, and should only be used on a
case-by-case basis. Runic fonts should have the ZWJ pairs encoded in
the glyph tables.

I wonder if it wouldn't be useful at some stage for me to pick the
best bits out of my papers and do them up as a Unicode Technical Note.
