That doesn't work because then how do you display $a$ as literal inline code?

What about:

    Inline code is ` $a$ ` automatically trimmed

But I think $`a+b`$ makes more sense (or even $$a+b$$; I mean this is markdown after all, not LaTeX).

True, but it is TeX notation, and `$$ $$` for inline math goes deeply against the experienced TeXnician's intuition. Why intentionally use notation that violates some users' domain intuition when there's an alternative that's no worse?
