Cosmetics: you could remove the ``meta_type`` since this is only relevant when installing new things.
It also has the side effect that if there is a *Dexterity* ``Topic`` FTI (because someone has replaced it), this would change it back to an *Archetypes* FTI .. Therefore I'd remove all ``meta_type`` attributes from the ``uninstall`` profile since it does not create nodes.

I think ``xmlns`` and ``i18n:domain`` is also not necessary here - we don't need to translate removed things :wink:
