Yes, there was a suggestion in the early reviewing to keep it simple and
delegate the unpacking of the dependencies to the go tool instead of
duplicating the logic.

I think the approach taken by Khem in for example the influxdb recipe by
patching the go.mod file with a module replace to a fork fits most cases as
you need the fork to do the PR anyway.
Then there is the alternative of doing the module replace with a local
directory if you want to keep the module cache untainted.

I see two main alternatives. Either to continue letting the go tool
unpack the
dependencies but triggered earlier in unpack task instead of compile
task. Or
let the gomod and gomodgit fetchers unpack fully.
