Sure, an environment variable would work just fine for our purposes. It would probably also address the concern that users may disable all advice and then miss out on some information. > > It has happened multiple times to us that new advices were introduced > > that then subsequently caused regressions in Gitaly because the output > > of Git commands now looks different.

Filtering out advices would be doable. But we probably wouldn't want to do so unconditionally whenever we execute Git commands. Which would bring us back to the point where we have to address these new advices whenever they come up, and it wouldn't be much less verbose than to just disable advices we face. Patrick
