I just realised another reason why this upload is important - I use
http://packdeps.haskellers.com/ RSS feed support to notify me when any of
my packages have out of date dependencies. Unfortunately, I haven't
actually got any notifications about my packages not building with GHC 8.8,
so I'm having to rely on users reporting issues.
