For some reasons I like to align top of indices regardless if variable has exponents or not and if exponent is a, 1 or g, p, q, y. With use of package [low-sup]{subdepth} the aligning is improved, hover small differences in positioning still remain.
Is it possible to improve subdepth package so that manual tweaking of indices positions become unnecessary? Or exist similar newer packages with more independent indices align?
\documentclass[12pt]{article}
\usepackage{fouriernc}
\usepackage[low-sup]{subdepth}
\begin{document}
\Huge
\[ x_a,\quad x_b,\quad x_B, \]
\[ x_a^2,\quad x_b^c,\quad x_b^p, \]
\end{document}
Result without subdepth package:
Result with `subdepth package:


asubscript to be at the same depth as the top of thebsubscript? That seems very unnatural to me...for example, same baseline would seem to be a more natural request. – Steven B.

Your answer in given link is intriguing! – Zarko May 21 '20 at 18:28
