[css-text-4] prioritized hyphenation may be incompatible with hyphenate-limit-zone

[frivoal]

I believe that css-text (3&4) try to be silent on the concept of prioritized hyphenation opportunities not to rule them out, but to leave them up to the UA, as a matter of implementation quality.

However, It seems to me that the concept of prioritized hyphenation opportunities is at odds with the hyphenate-limit-zone property from level 4. As currently defined, it seems to require that parts of words be pulled back from the subsequent line to fill the current one once a certain threshold amount of white space is reached, and that does not seem to allow for prioritization, since you have to pull whichever part of the word will fit when you get to that point. Maybe that should be changed to also have an auto value that would allow for prioritization, and/or to have two values rather than one: one that indicates the minimum amount of left-over space before you're allowed (but not required) to hyphenate, the other one being the maximum amount of left-over space before you're required to hyphenate even if that means using low priority hyphenation points.
