Valid point, we'll need to add that. I'll put it in version 2.1 of
the design.

Basically this is an upgrading problem and is already covered by your
third point.

This is very much related to the first point: since the UI doesn't
show this flag you obviously can not toggle it

Personally I'l look the term `Auto' more, to note that installation
and removal for these packages is done automatically.

It doesn't make any sense at all, so it should be disallowed.

You want to use the global flag to initialize the Auto/Hooked flag
probably.

No it does not, since it a apt-specific thing dpkg does not need to
know about it, since apt will just call dpkg to do the work, not
make the decisions.
