[Are there any open research problems in the world of TeX?](https://tex.stackexchange.com/questions/128454/)

It's been raised that this question is a [big-list](https://tex.stackexchange.com/questions/tagged/big-list "show questions tagged 'big-list'") and should be community-wiki.
Am I the one who would have to make it community-wiki,
 or could that be done by a voting process?

Obviously I'd like to not lose the rep,
 and my better judgement / pesky humility is telling me that it should be CW,
 but does such a voting system exist for that?
Frankly, I'd feel better if I thought that everyone agreed that it should be so.
