I looked over the patches and they look pretty good in general.  There’s
just one little thing, which I realize is a little annoying.  We try to
follow the Stackage LTS versions of packages where possible, as they are
chosen carefully to work together and with our version of GHC (8.4.3).
Right now, we are on Stackge LTS 12.14.  Could you please go over these
patches and downgrade them to their Stackage LTS 12.14 versions (which
can be found at <https://www.stackage.org/lts-12.14>)?  You can also
import directly from Stackage, using (for example):

    guix import stackage --lts-version=12.14 validity

That may be the fastest way to fix up the packages.  I would do this,
but you’re in a better position to judge whether the packages still do
what you intended them to do, since I imagine you have a use-case in
mind.  :)

Thanks!
