I will have a look.

It is worth it since then we have a lot more information to do cool
things with.

The suggestion thing was just an idea. You can also use the links to
show related documents for the activity. However, as the documents would
not be linked directly but via the event the link would automatically be
"marked" as being added automatically and thus, less important than a
manually added one.
When I say "suggestion" I do not necessarily mean to suggest the link
between file and activity but any kind of suggestion. This includes
suggesting the file when showing related stuff for an activity.
