Specific things that are important enough to trigger such discussion
here could be made non-fragile if they had existence in MathML as
empty elements. A few examples suggested by LaTeX include
<leftarrow/>, <longleftarrow/>, <rightarrow/>, <longrightarrow/>,
<mapsto/>, and <longmapsto/>.
I don't imagine more than a few hundred of such empties.
