Maybe then I did misunderstand brian.

With this series, traces will always be emitted to location where
GIT_TRACE2_EVENT indicates, or default location. Like before, if the
user asks for --quiet or equivalent, the user will not see "Resolving
deltas... (4/30)" in their stderr.

Before this series, when a user indicated --quiet or equivalent, the
traces were not emitted to GIT_TRACE2_EVENT's location, because the
progress struct was not created.

I figured brian was saying "we'll still honor the --quiet flag if the
user doesn't want to see ["Resolving deltas...blah blah" in their
stderr]", and that is true. The traces will be logged but the
user-facing output on stderr will be suppressed.
