Please don't worry about hypothetical questions such as these.

If you are going to go looking for problems, then it is actual
examples of problems that are useful.  For example, if you could
find a spacing problem with @displaymath, that is something we
could discuss.

Otherwise, discssing hunches of where problems may occur, while
leaving it to others to fill in the details, isn't particularly
useful methinks.
