Docs: is it documented anywhere that awsParam and awsSecret usage makes env var @required?

Is it documented anywhere that awsParam and awsSecret usage makes env var @required?
What is similar behavior for exec()? If nothing is returned, does it error? I could not find in docs.

I think what you are encountering is the behaviour of @defaultRequired=infer which sets the item to required if anything is set - whether it is static or a function call. You can also just set @defaultRequired=false (or true) and use @required/@optional to set accordingly.
