Table 1 in the paper looks promising, though. Let's hope their estimation is correct:
We implemented 5 a new build sys-
tem for GHC from scratch using Shake and our build abstractions
from §5. The new build system does not yet implement the full
functionality of the old build system, but we are currently address-
ing remaining limitations; nothing presents any new challenges or
requires changes to the build infrastructure.
