@klaas019 Could you ammend the commit message so that it reflects this PR a bit better?

Also, would you mind referencing which PR originally removed the file?

[klaas019]

Is that correct?

[cmonr]

Close but not quite.
The commit itself should be updated to reflect the changes.

Take a look at git commit --amend to modify the commit mesasge.
