I have a lot of #+begin_example with language in my notes. In the 
beginning I accidentally discovered that code is highlighted accordingly 
to language syntax, so I continued to use this feature for snippets that 
are not intended to be evaluated. Later it was a bad surprise that 
export does not preserves highlights. So for me #+begin_example is a 
shortcut for #+begin_src with :eval never (that can be specified as a 
property).

 From my point of view exporters may reuse code block formatters for 
examples. It would allow to pass options to e.g. LaTeX verbatim environment:

Notice that subscript still increases inter-line space a bit.

git blame gives 0618aeafb39dbf78e753348eaeaddbb7f8104cd0
It seems smaller font breaks horizontal alignment in tables.
