I have opened the gomodule mode with GO111MODULE="on", trying to download the packages in the $GOPATH/pkg/mod.
Specifically, the remote repos mixed Capture and Lower case of words in it.

We expect to see the package with the exact same pattern of the remote repos. e.g.

What did you see instead?

Instead in the $GOPATH/pkg/mod, it is shown as!ablock!time/!big!data, every Cap word in the path has been translated as ! + <lower_case word>

To avoid ambiguity when serving from case-insensitive file systems, the $module and $version elements are case-encoded by replacing every uppercase letter with an exclamation mark followed by the corresponding lower-case letter. This allows modules and to both be stored on disk, since the former is encoded as!m.

As seankhliao noted, this is expected and documented. I'm closing this issue as working as intended.
