We could output that kind of code based on a customization variable too.
Should \usepackage{unicode-math} replace \usepackage{amsmath} or should
it be there in addition? And is \usepackage{amsfonts} needed/useful if
\usepackage{unicode-math} is in the header?

We should add it by default, as we have ways to get a title that should
make sense, using @settitle or other possibilities as we do for HTML
output.
We cannot know if there are characters that would be problematic, both
in alt= for images and in the pdftitle=. Which characters should be
escaped and how? Is that described somewhere that could be used for all
the graphicx/hyperref options?
