# Problem During the review of https://gitlab.com/gitlab-org/gitlab/-/merge_requests/140522 Auyfan suggested that we should only expose the new canceling functionality for supported runners. If we had ommited this, jobs would have transitioned to `canceling` briefly before being marked `canceled` even for runners that don't support running `after_script` during `canceling`. As a result, we put the support for transitioning to canceling behind a runtime runner feature check for the `cancel_gracefully` feature. To roll-out the support for running after script during the canceling phase we will need to have the runner send over that it supports the feature. # Proposal Ensure that versions of the runner that support after_script are sending over that the runner supports the `cancel_gracefully` feature. See the rails check: https://gitlab.com/gitlab-org/gitlab/-/blob/3d88e491ec0819488bb6ffa636bbf2a5bb2f9e66/app/models/ci/build_metadata.rb#L71 cc. @ajwalker
