How do we do that? Adding git repos to SWH is something I can achieve,
but adding tarballs to SWH was always opaque to me.

I find no reference in the manual about Disarchive. Ideally, is there a
linter for just adding a package to the disarchive database?

For git, I know and appreciate that the linter can directly add a
missing repo to SWH. During linting, I recogniced this is missing for
hg.

I was thinking a second time about it and found that not only the newer
development of OpenJDK is on GitHub, but also the older versions are
available. So I could add another patch like this: 

+              (method git-fetch)
+              (uri (git-reference
+                    (url "https://github.com/openjdk/jdk9";)

WDYT?
