I think https://github.com/w3c/webappsec-subresource-integrity/blob/master/signature-based-restrictions-explainer.markdown should redirect here.

agreed. Do you know how to set this up in Github?

(I mean .. I can delete and say "this has moved" but if there is a way to redirect, that would be great)

I don't know how to do an actual redirect, sorry.
