That might break existing code which looks at minibuffer-completion-table.

(my-special-table toto) is a valid completion table.

Yes.  They'd be sub-types of `function'.

I kind of like the idea of adding such a functionality because it would
come in handy in stream.el and nadvice.el (could improve performance of
stream.el, and would clean up the hackish part of nadvice).

This use for completion-tables is not a good justification to introduce
the feature, OTOH.  We could use this feature there if it's available, tho.
