But that can not guarantee whether the app creation would complete successfully. Say that the git repo creation(or any other task) failed due to a network error or some other serious issue. Then retrying will not solve the issue. IMO, what we need in the first place is the rollback functionality and as an improvement we can do the retry logic. WDYT?
