Do us naïve users need to change our workflow with these submodule changes?
Probably yes... to some extent at least; that's why only haddock.git has been converted for now[1]: to find out empirically what's involved before continuing with the submodule-conversion. I've tried to describe one possible workflow (for if you need to publish a modification to haddock.git) at https://ghc.haskell.org/trac/ghc/wiki/WorkingConventions/Git/Submodules#Maki... I hope it makes a bit of sense :-) IMO, it's quite useful to familiarize oneself with the 'git submodule' family of commands, and especially 'git submodule' and 'git submodule summary', as those two introspection commands allow one to get a better picture in which state the currently cloned GHC working tree's submodules are. [1]: OTOH, haddock.git is not the first/only proper Git submodule we have so far; so, in some way this isn't much of a change...
