I agree. Suppose we had a "git commit-graph remove" sub-command that
removed the commit-graph file (ignoring that there are probably better
hypothetical examples than this ;)). It's not obvious what --progress
means in the context of that mode.

Here's a patch that does what you and Gábor are suggesting as an
alternative. Unfortunately, we can't do the same for the
multi-pack-index command, since the analogous change there is 60ca94769c
(builtin/multi-pack-index.c: split sub-commands, 2021-03-30), which was
released in 2.32.

Anyway, as promised:

Subject: [PATCH] builtin/commit-graph.c: don't accept common --[no-]progress

In 84e4484f12 (commit-graph: use parse_options_concat(), 2021-08-23) we
unified common options of commit-graph's subcommands into a single
"common_opts" array.

But 84e4484f12 introduced a behavior change which is to accept the
"--[no-]progress" option before any sub-commands, e.g.,

    git commit-graph --progress write ...

Prior to that commit, the above would error out with "unknown option".

There are two issues with this behavior change. First is that the
top-level --[no-]progress is not always respected. This is because
isatty(2) is performed in the sub-commands, which unconditionally
overwrites any --[no-]progress that was given at the top-level.

But the second issue is that the existing sub-commands of commit-graph
only happen to both have a sensible interpretation of what `--progress`
or `--no-progress` means. If we ever added a sub-command which didn't
have a notion of progress, we would be forced to ignore the top-level
`--[no-]progress` altogether.

Since we haven't released a version of Git that supports --[no-]progress
as a top-level option for `git commit-graph`, let's remove it.
