Come off it, Dan, anyone who used a typewriter knew the trick of lifting the
roller a smidge (or lowering it) for sub (or super) script. You must not have
ever typed footnotes.

The reduced font size of the "th" is more than slightly a problem for
your argument in this case.

And there is still the problem of proportional font spacing.

Etc.
