Custom Task Runner Use Cases Affected by Removal in 21

[joshlartz]

I wanted to take a minute and inform the team of the myriad of other ways we use custom task runners, beyond what the blog mentioned. I don't see how any of this will work after Nx 21.

In no particular order

• The ability to skip cache in a CI run for one off issues
• Reading our feature flag implementation and differing behavior in executors and generators
• Analytics about what executors were used, how long they took, and the like
• Checking package dependencies to ensure they conform to specific version ranges we define
• Blocking execution if critical config issues are detected
• Remote caching to S3
• Integrating Nx with Projen for scaffolding and updates to files

As you can see, a lot of it is run once/at the beginning use cases that only task runners provide. It gives us guardrails and integrations with other tools. If root tasks were a thing, it might work, but task runners are at the perfect spot to do all of these things today.
