Well, a lot of classical documents that are visibly structure-dependent omit punctuation. This is most commonly the case with things like poetry. A lot of old texts do use simple punctuation (like stops) though.

You're going to get spacing compression when pushing a full-justify most of the time, or you have to allow a 1-character margin for hanging pronunciation. I'm not positive how this impacts parentheses (probably forces early break and hanging if not respaced)

Most Chinese I read is left- or top-justified only and leaves ragged edges, and general Asian typography rules indicate what characters cannot begin or end a line.

If you want perfect monospaced gridding, you omit punctuation.
