Please confirm these before moving forward.

• I have searched for my feature proposal and have not found a work-in-progress/duplicate/resolved/discarded issue.
• This proposal is a completely new feature. If you want to suggest an improvement or an enhancement, please use this template.

Describe the new feature

Currently not all commits in this repository are signed. I think all commits should be signed to ensure origin authenticity.

Describe how this new feature could help users

Prevent unauthorized code changes.

Can GitHub actions/bot accounts sign their commits?

Nevertheless, all the bot PRs are checked before merged.

I see, I wasn't aware these were bot commits. I'm not sure if it's possible to get those signed.
