And even diacritics could be omitted and it'd still be super duper useful and cover 99%+ of use cases (Hebrew is almost never written with vocalization).

Hebrew doesn't have ligatures or any complex font behavior, at least for letters. I understand that Arabic and Farsi is very complicated.

Proposed technical implementation details (optional) Having Hebrew glyphs supported in a modern terminal font would just make the experience work well out of the box. Very, very few Monospace fonts actually work with Hebrew, and using font fallback isn't a good solution (look at what it does). In general, in terminal contexts, using Hebrew is a total nightmare. Basically, include Hebrew glyphs in Cascadia.
