No. Those are much more flexible, as they are run either after activation or
just
before deactivation. They can be class methods, what have you. Uninstall is
simply
an exception, and so in 2.7 uninstall.php was introduced so uninstall
scripts can be
isolated and more robust.

Not one bit. Use uninstall.php if you want flexibility, or
register_uninstall_hook if you
want simplicity. Bottom line is, we're executing code when a plugin is not
active, so we
need to be nimble about it.
