is process.shell officially supported?

[briankegerreis]

I am trying to set a pipeline to run all script blocks with pipefail, and a solution I have seen is to set process.shell to ["/bin/bash", "-ueo", "pipefail"]. However, process.shell isn't documented, and I have only seen it pop up in some nf-core pipelines and on Gitter. Is this safe to use, and if so, is there a reason it is not in the documentation?

'shell',

You are right, it was never documented but it's safe to use.
