You need additional tooling to make use of Commit-Id. With Gerrit, it does link them all together.

... no. Each patch has a purpose, which will be described in the commit message. Hopefully it does what it says it does, which you can compare with its current diff.

If it was upstreamed with minimal changes, then the diff is near-empty. Drop it.

If it was upstreamed with significant changes, then the diff will be highly redundant. Drop it.

If the diff appears to do what the commit message says it does, then it probably does what it says.

If the diff is empty, either it was upstreamed or you fucked up rebasing. Don't be negligent when rebasing.
