I propose we make the locking support optional rather than on by default, as it's prevented many workflows from happening so far to be a maintenance burden and sometimes still does. It doesn't serve the regular desktop user very well IMHO, but it's a valid use-case that fits the CI/automation needs. I propose we have a flag or environment variable like

STACK_LOCK=true

Or something like that to enable it.
