I think what we can do is stop having polls as their own type of content.
They are an add on module, like upload (file attachments), nodevote (votes),
...etc.

In other words, they add polls on the form of any type of content that the
admin assigns it to be. So, we can have blog polls, forum polls, page polls,
...etc.
