Git plugin calls fetch twice per checkout

When performing a git clone operation,

git-client and git-plugin both triggers a git fetch.

Below are the two lines of code running in the same git clone command both doing fetches.

The second link is part of the GITSCM step, it triggers the git-client-plugin's CloneCommand (first link) to perform the clone operation. And afterwards, the GITSCM step performs a fetch once the CloneCommand Completes.

However, within the CloneCommand (first link) itself, a fetch command was already done.

I am aware there are needs to support for git clone to fetch all refs first -JENKINS-31393-. The suggestion provided in that ticket was to use "honor git refspec", so shouldn't "honor git refspec" skip the first fetch here?

Thanks,
