For stacked commit workflows which merge into main with squashing I tend to:

- create an empty commit with the branch name, type, ticket number etc. (with a small git script, `git issue 321 fix some things` -> `git switch -c 321-fix-some-things && git commit -m "fix(321): some things" --allow-empty`)

- `rebase -i` then shines when you have stacked commits where previous one have been merged _in a changed form (e.g. squashed)_. In such cases git often duplicates the already merged commits thinking they are part of your branch leading to endless dump conflicts, with a "marker" commit you can easily spot it in the `rebase -i` view and then also easily stripp them out by removing their lines
