Well, my use case:
I use several sub-namespaces as follows:
members:profile
members:place
members:school
I want my users to just click a quick button (using the
interwiki plugin and will convert highlighted text (e.g. Chicago) to:
[[place>Chicago]]
Instead of clicking a few buttons for the link in order to attain the same and come up with:
[[:members:place:chicago|Chicago]]
Or manually entering:
[[:members:place:Chicago]]
Moreover, I liked the icon attached to each link when using Interwiki-links, but I am willing to drop that feature if I could just make Backlinks and Orphaned Pages work.
