Took the NSURLDownloadSPI trick from Dan's patch in bug 184225.

This doesn’t seem to include a crucial (at the time) bit of that patch. Namely, as it stands, this patch appears to have a public header (WebDownload.h) importing a private header (NSURLDownloadSPI.h). Not a problem?
WebDownload.h appears to be a private header, am I missing something?
WebDownload.h is re-exported by WebKit as public on macOS, which is fine. NSURLDownloadSPI.h is not imported on macOS.
