Experts. Optimising your whole notation for beginners is pre-emptively putting up a skill ceiling. Beginners stop being beginners (at which point they’ll outgrow the beginner oriented syntax) but experts will remain experts.
Instead, optimise for teaching/learning the skills better rather than capping everyone’s skills. The presence of a learning curve is not an inherently bad thing.
Edit: re-reading your previous comments, I think you and I are in furious agreement haha
