Thank you very much, this is really interesting!

A few remarks:

I don't believe it's very accurate to say that only Babel and
Polyglossia will be affected by new types of patterns, the main change
will be in the engine, and it will certainly be only in XeTeX and
LuaTeX, Babel and Polyglossia just tell the engine to use a different
set of patterns, they don't really know anything about hyphenation, and
it's even possible that they won't have to change anything. But that's
not really important.

Also, the current problem (hyphenating "co-mi-da" but not "come") cannot
really be solved at hyphenation definition level.

Something I didn't understand is how many different weights you can have
in a word in an hyphenation definition? Two is clearly possible in your
document, but it's not clear if more is allowed, nor if there is an
upper limit, the document would be clearer if this is precised.

Is there a pattern definition corresponding to this new hyphenation
definition? Or could it be translated to the current pattern format?

If I understand correctly, from TeX point of view, this would mean
adding the following penalties:
 - \hyphenpenaltyweighttwo
 - \hyphenpenaltyweightthree
 - \hyphenpenaltyweightfour
 - \hyphenpenaltyweightfive
 - \hyphenpenaltysuffix
 - \hyphenpenaltyprefix
 - \hyphenpenaltycompound
 - \hyphenpenaltycompoundsuffix
 - \hyphenpenaltycompoundprefix
 - \hyphenpenaltycompoundinterfix
 - \hyphenpenaltyunfavorable

? But this would make sense only if there was a pattern definition that
TeX could read of course.

Thank you,
