I chose this translation because
1. It was the easiest to implement;
2. It is the closest to what Org (unlike to LaTeX) really sees;
3. It doesn't matter since it is a pathological case.

I strongly disagree.
Org is not a front-end to LaTeX. LaTeX is but one of its export output
formats. In most of the others, sup/superscript doesn't force math mode
on the user.
In Org, if you want to enter math mode, you need to explicitly request
it, e.g., with:
a_{$1 + 1$}

Exactly.
