Using submission #63647 [1], now it raises:

Note that these warnings are non-blocking and thus a list of Guix
packages can be generated, although some are partial.

Well, I do not know if we can do better.  I mean, the issue seems about
a wrong packaging upstream.  I mean, the tag v0.41.1 is reported as
metadata from goproxy (https://proxy.golang.org) but then the real Git
repository of the package does not contain it.

Other said, the importer first queries goproxy and get metadata.  This
lists available versions;  v0.41.1 is part of this list as reported by
the hint:

$ ./pre-inst-env guix import go

hint: Pick one of the following available versions: 0.42.0-rc.1 0.41.1 
0.41.0-rc.2 0.41.0-rc.1 0.41.0 0.40.0 0.39.0 0.38.0 0.37.0 0.36.4 0.36.3 0.36.2

0.16.0 0.15.1 0.15.0 0.14.0 0.13.0 0.12.0.

Second, the importer Git clone the repository.  You can access to the
cache (replace ’simon’ by your username on your machine :-))

Well, I do not know if there are conventions in the Go ecosystem that
points to other tags.  For sure, some tags are there as expected and
then after v0.24, no.
