Yeah, +1

I agree that some heuristics to figure out the file-name from 
(svn-reference-url ref) would be nice.

It's not that important that the store filenames are meaningful to humans, it's 
just nice-to-have.  So I'd say heuristic it and be done with it.

On second thought, maybe even default file-name to the Guix package name (if 
possible at this point in Guix).  The hash value will make it unique regardless 
(for example if there are multiple svn-download blocks in the same package)
