According to the rules for inactivity defined in [RFC-0025](https://github.com/cloudfoundry/community/blob/main/toc/rfc/rfc-0025-define-criteria-and-removal-process-for-inactive-members.md),
the following users should be removed from ARI approvers/reviewers/bots:

@mrosecrance
@mvach
@Cryogenics-CI
@joefitzgerald

According to the [revocation policy in the RFC](https://github.com/cloudfoundry/community/blob/main/toc/rfc/rfc-0025-define-criteria-and-removal-process-for-inactive-members.md#remove-the-membership-to-the-cloud-foundry-github-organization),
users have two weeks to refute this revocation, if they wish by commenting on this
pull-request and open a new pull-request to be re-added as approver after this one is merged.
