Yes, both issues relate to "point 6", i.e. the API.
Yours is non-modal (well, the minibuffer is not 100% modal, since you
can do something else while a minibuffer is open, especially if you set
enable-recursive-minibuffers, but it imposes a strict nesting).

The idea of integrating the two, is that users can then use yours
without changing the corresponding code to use your API.  Users could
choose which interaction mode to use for which commands.  Or even
provide a command to dynamically switch interaction mode directly from
the minibuffer.

To get a vague idea of what I'm talking about check
`completion-styles' as well as `completion-styles-alist'.
