Many thanks for your reply, Hans.
I reported the issue in the opposite way it happens:
\definefontfamily[mainface][rm][MinionPro]
\definefontfamily[anotherface][rm][TeX Gyre Pagella]
\setupbodyfont[mainface]

The ff-ligature prevents hyphenation with TeX Gyre Pagella, but not with
MinionPro. (This is the opposite of what I reported before.)
it depends on the complexity of the ligature .. ff is not so much an
issue but you can have ff + i = ffi etc and we need to deal with kerning
too (it depends a bit on how the opentype features are applied and we
can handle quite some weird ligature implementations)
the latest mechanism in context can deal with quite some situations but
at some point has to make decisions (in order not to loose for instance
kerns; double chained ligatures would result in way more overhead and is
not worth the trouble)
one might wonder if we never had these f[fil] ligatures of if ancient
technology had provides hundreds of them combining upto 4 characters etc
etc.

MinionPro. (This is the opposite of what I reported before.)

I never do it. Reported only for the record.
Sorry for the previous inaccurate report. Many thanks for your help,

Re: [NTG-context] bug in hyphenation?
So your problem has nothing to do with Greek hyphenation, it’s about the way
you define your \CritApp command. You could have shown the same problem with an
English text. It appears that injecting the word via your macro breaks
hyphenation, but I assume Hans and Wolfgang will know better about that.
Example without Greek:
\showframe
\mainlanguage[en]
\setuplanguage[en][patterns={en, agr}]
\definepapersize[HippPaper][width=6in, height=9in]
\setuppapersize[HippPaper]
