Inline constructClasses().

Remove the actual method body for constructClasses() as it is no longer
needed. I've left a no-op method to make life easier for people if they
are following 3.0.*-dev. Removing the method now would cause seemingly
random test failures now. Instead I'd prefer to remove these methods
after we've done a release announcing their removal.
