Once upon a time we used a dependency graph to order uploads. I think
we more or less abandoned that when we switched to mostly tracking
Stackage LTS versions or when we developed the package-plan tooling or
some other milestone I can't remember.
The current situation is that
(a) Because of the haddock-interface change, every single package
needs a sourceful upload. This isn't relevant for Ubuntu.
(b) All packages need to be updated to the version in the
package-plan, which generally corresponds to Stackage LTS 15.13.
(c) Both packages which do not need a version update and packages
which do need to be upgraded also need patching because we do
not automatically apply Hackage metadata updates which help
keep Stackage consistent.
(d) All new packages pulled in as dependencies of the new versions
need to be packaged, and get processed through NEW. Some of
these packages have been stuck in NEW for weeks, but most of
them have not been packaged at all.
(e) Build/test failures need to be addressed.

Judging by the current rate of progress, I think it will be quite a while
before all the Haskell packages in unstable are buildable.
Thank you so much Clint for summarizing the current state!
In that case I can't really help much right now. I can't help:
- you as I'm a haskell-noob
- the packages in Ubuntu as we just have to wait until (a-e) as you outlined come together correctly.
Any upload that you do will be auto-synced to Ubuntu and tried there anyway, so for now we will follow what you do in Debian to resolve this without further action.
FYI - since I was checking test results, build dependencies and build results the two cases that seemed not to be "just build dependencies" are:
- riscv64 FTFBS  (it seems we have the risc build dep, while on  it seems Debian hasn't)
- autopkgtest issues for GHC . Since eventually everything will lock on GHC to migrate together this needs to be fixed sooner or later.
- currently these all seem to be related to haddock-interface , but once that is resolved the tests might need a retriggering
Once you think Haskell is in an overall good shape again
with all pieces of the puzzle matching each other and things should build let me know.
I can then recheck if - by then - Ubuntu needs to trigger any rebuilds or tests for it.
