And, I mean things like being able to take tasks, pipe them through whatever tooling you like, pipe them back in, sync them from any other task system, etc. TaskWarrior has a fully customizable priority and urgency system, tagging, dependency management, and status system. I also like that TaskWarrior is usable completely offline and then can be resynced whenever you feel like it.

Vikunja is great and probably the right choice for most people. But if you do significant project planning for yourself AND want to be able to deal with you todo list programmatically, the only other thing close is orgmode.
