As an alternative to Allow 'cylc reload' to reload global configuration by ScottWales · Pull Request #6509 · cylc/cylc-flow · GitHub?
The PR will allow us to reload the global config for all running workflows like this cylc reload '*' --global. It will also reload the workflow config in the process, but since we’re not reinstalling the workflow this config will not have changed. Note reloading the workflow config is kinda required for changes in the global config to take effect.
