One use case is education, where a web app is often easiest to build and deploy.
There are lots of rooms equipped with computer, notation software and keyboard in music institutions, where webmidi seems like a great way to develop some quickie music theory/education apps.
The web is not anywhere near parity for music and audio production yet, but its proponents see webmidi as one necessary step to that direction.
(I would personally not use current webaudio/webmidi software, but have successfully deployed a lot of it for education!)
