Do we need the add_axobserver? it is already handled by toolmanager and as far as I know MEP27 is going to be used exclusively with toolmanager.

Not sure... can leave it for a later refactor if someone feels inclined :P.

I do think this a bit too complicated for now as this will depend on the backend... i.e. if one added backend specific widgets to the thing that have a different method name to destroy (assuming they have one).

So for now I would rather leave this open like this, leave the class that created the items have the responsibility for cleaning them up.
