I had a look and indeed, it is not easy at all to customize that part of
the output.  One possibility would be to use a different 'translation'
of the string '{number} {section_title}' with @inlineraw, but I think
that it is not possible right now to override the 'translations', and
also it would be quite cumbersome.

Then there is the possibility to replace the heading formatting function
entirely, by replacing the _default_heading_text formatting function
with:
texinfo_register_formatting_function('heading_text',
                                     \&my_heading_text);
and doing something different if the command is a sectionning command.
Not sure how this would be easy or hard.
