Summary
Allow the
--timeline
option even if a phased command does not support parallelism.Details
Today, the
--timeline
option is only available on the command line if a phased command supports parallelism.However, this option is useful in many cases even if there is no parallelism -- the histogram can help identify visually which projects are bottlenecks in the execution flow, and the summary at the end is helpful for showing the breakdown of total time spent in the different phases across all projects.
