That's quite likely the case, either directly or indirectly. When changing
the dependency graph, especially involving `.hs-boot` files, it happens
quite easily that one needs to give the build-system a hint and make
implicit module-graph dependencies more explicit by adding an explicit
`import SomeModule ()` in the appropriate place. You may find commit of
mine where I did things like that in the past.
