we (luatex team) are starting to worry about this kind of accumulated patching because it all interferes so one option is to delay these patches till after the 2025 code freeze
Sure, I don't mind if it will get in after the code freeze.
one can make a point that if we have directions at all, short skips should never kick in and that one should handle it either in macros or in lua callbacks where one can fine tune for a specific situation
Yes, isn't it why \matheqdirmode exists in the first place? I'm just wondering how useful is this mode primitive if using it results with unpredictable skips.
these three-dir-var relates heuristics are messy
Just for fun, I wondered how luametatex deals with it, as there are parfillrightskip and parfilleftskip to consider, which complicates things even more... Udi
