How do you foresee an implementation for this? This has to be in the

new symbol in the patterns (œ, )?
the problem with that is that we get a more and more complex routine
which degrades performance, makes it hard to configure and explain, even
not intuitive
anyway, because in a glyph the left/right fields store the current
values of left and right hyphenmin it's not too hard to run over the
list using a callback and adapt that value (the first one in a word)
- identify start of word
- look at left value of the first glyph
- see if there is a char in the #left glyphs that you want to count more
or less times
- and adapt the left value accordingly
something like that perfectly fits in the concept of luatex: extending
or manipulating existing (simple) mechanisms via callbacks
