According to Develop Against Any Org, there's a new (at least new to me since Summer '19) option -o
for the sfdx deploy command as follows:
sfdx force:source:deploy -o
Documentation says:
Regardless of whether the deployment contains errors (not recommended if deploying to a production org)
What would be a good use case for this? And would there be any good use case to ever deploy to production for this?
