from my experience, only some specific features will break. I don't
think that the phpMyAdmin team has collected a list of these features.
For big databases, however, there will be a performance problem, as
phpMyAdmin relies extensively on information_schema, whose performance
with MySQL < 5.5 is worse.
Maybe we can extend phpMyAdmin's 4.0 life (for security fixes).
