In that sense then yeah there would be an issue. I was talking about someone
using a plugin that was written in a version prior to the implementation.
Say we put it in version 2.5 (3.0 would be more likely), then plugins that
are authored for that version wouldn't work in 2.X, unless they added the
above check. However - plugins authored pre-loader would still work in WP
with the loader due to the head hook.
