Sure. For me it involved some manual effort. There might be a more clever 
way to script it that others can share, but I didn't think it was too bad, 
and it allowed me to make notes about what problems I observed as I 
encountered them. Nothing I did was Go-specific. Perhaps a small project 
for another time, we could add a cookbook recipe for testing upgrades to 
languages or other packages with many dependents.

Here's what I did after changing the default go:

* ran `./pre-inst-env guix refresh -l go` and recorded the list of 
packages to build.

* ran `./pre-inst-env guix build` with that list.

* After a while there is a build failure, and the end of the log looks 
like (the actually failure here is unimportant):

```
FAIL	go.etcd.io/bbolt	600.127s
FAIL
command "go" "test" "go.etcd.io/bbolt" failed with status 1

Some deprecated features have been used.  Set the environment
variable GUILE_WARN_DEPRECATED to "detailed" and rerun the
program to get more information.  Set it to "no" to suppress
this message.

* From this, I make a not the go-etcd-io-bbolt has a build failure, and 
that I was unable to attempt chezmoi.

* I remove chezmoi from the list of packages to build and re-run `guix 
build`.

Repeat that process until all the remaining packages build, and you should 
have a nice list of build failures and builds that could not be attempted.

Hope that helps,
Jack
