Thank you for answers!

I understand, that Typst is very young now, and can not support all spread of typographic features, questions are about flexibility of internal architecture, which can (or cannot) allow to support all these features theoretically without global re-design.

I've started to plan something like this several times in last 20 years, but always dropped project (as it was pet-project for me) due to understanding that it is very hard design problem.

Good luck to your project! IMHO, we need something like this!

(and, yes, (14) was tongue-in-the-cheek question, sorry).
