You may have to get multiple teams to review your change before being allowed to commit it. And you have to run all their tests. If there is a problem the whole thing will typically get rolled back, which is a drag because then you have to fix the issue, run tests again and get approvals again.

So, in practice, for large-scale changes that affect many teams, we still try to break up large patches into multiple smaller steps, even working in a monorepo.

A single commit is nice for small patches that only affect a handful of teams, though.
