Have we lost this ability?

I don't see an option for it. For some characters there are unicode options: all numerals, plus, minus, parentheses, and some letters: ⁰¹²³⁴⁵⁶⁷⁸⁹⁺⁻⁽⁾ⁿ ₀₁₂₃₄₅₆₇₈₉ₐₑₔₕᵢⱼₖₗₘₙₒₚᵣₛₜᵤᵥₓ

We can also just type out LaTeX in code blocks.

$\int_{a}^{b}f^{\prime}(x)dx=f(b)-f(a)$

It'd be much nicer if the site supported MathJax or similar, though of course you can add that to your own browser through an addon to typeset LaTeX inline. And it doesn't even support Markdown, still uses BBCode, so I don't really expect modern functionality!
