I think the ConTeXt and LuaTeX people do not care too much about
compatibility (which is the right thing IMO, we have to move forward).

These typographic ligatures should still work. Only the ligatures that
are input methods in disguise (for dashes, quotation marks etc.)
should break.

Aha, it's not as easy as I thought. I just tested the following
document with TeX Live 2011's ConTeXt:

\usetypescriptfile[type-vista]
\usetypescript[constantia]
\setupbodyfont[constantia]
\starttext
--- —
-- –
`` “
'' ”
fluffiest
\stoptext

The dash ligatures still work, the others don't. With Latin Modern,
the typographic ligatures (fl, ffi) work as well. The quotation mark
ligatures don't work in any font.
