Why is this necessary? Not that I mind, just good to know why it was added.

The fundamental parts look really good! I would just change some of the behavior :)

Is this related to links or is it just something we have left out from before? Seems like this is something that has been missing on File regardless of links?

I think I prefer if the type is soft_link, external_link, etc. That reduces the level of conditional nesting - you can say if type == "external_link" instead of if type == "link" and link_type == "external". And then have the meta-groups be soft_link and external_link as well. It just reduces the confusion of which variables can go together. (No-one will think that they can just change the target from external to soft and still keep the file, for instance.

To add to the comment above: This should not be a KeyError. It should actually return the object that the link is pointing to.

I think the getter should first try to see if it is an object or a link, instead of forcing the user to tell it to expect a link or not. This is also how h5py works.
Should fix #1
Aims for compatibility with NWB NeurodataWithoutBorders/pynwb#629
