in views, the bibliography entry's title is 'node: title'

Yes, that's because a biblio node is just a regular node with a bunch of extra fields. I will look into your suggestion, do you know how to create aliases in views?

I'm pretty confident that the same goes for the 'image' module, the 'weblinks' module, and whatever other module that creates custom node types.
(It's certainly true for user-created CCK content types, even if that could also be overridden...)

Or not?

May I suggest just leaving this be, for the sake of consistency?
Views, as it is, requires knowledge of how content is built up internally. This 'fix' won't really change that.
