Of course, `org-latex-classes' is a template. But it doesn't apply on
table of contents. However, Org needs some ways to control them.
Therefore it needs to handle optional arguments in \section macros and
alike.

There are already other ways to control the alternative title. See

There is the ALT_TITLE property, which allows to set an alternate title
for a given headline.

You can indeed write a filter for headlines which would remove every
optional title (see `org-export-filter-headline-functions'). Though,
Aaron Ecay's patch should solve most of the cases: no alternate title
will be added if you don't use ALT_TITLE or tags:not-in-toc option.

You're welcome. But for the problem at hand, your patch isn't, IMO, an
acceptable solution.
