Positive credit is not the only purpose of attribution.

There's also the named authors not taking credit for something they didn't fully do, regardless of whether the credit goes to someone else.

There's also traceability, if the authors/provenance needs to be considered because of some kind of problem or potential problem -- technical, legal, security, or otherwise.

Advertising in git commits is not ever going to substantially discredit these people or hold them accountable.
