All reports of debian-watch-file-uses-deprecated-sf-redirector-method for the archive. The extended description of this tag is:
The watch file seems to be passing arguments to the redirector other than a path. Calling the SourceForge redirector with parameters like project prevents uscan from generating working URIs to the files and thus has been deprecated and is no longer supported by the redirector.
This tag has not been emitted in any package tested by Lintian.
