The squashed commit from the PR -> main will have a clean title + description that says what was added.

Usually pretty close to what the PR title + description are actually, just without the videos and screenshots.

Example:

feat(ui): Add support for tagging users

* Users can be tagged via the user page * User tags visible in search results (configurable)

etc..

I don't need to spend extra time cleaning up my git commits and force-pushing on the PR branch, losing context for code reviews etc. Nor does anyone have to see my shitty angry commits when I tried to figure out why Playwright tests ran on my machine and failed in the CI for 10 commits.
