Currently, if we cannot read a CAfile or a netrc file while executing a built-in fetcher, we are silently acting as if we were NOT passing such files.

@pennae suggest we should fail if this comes to pass.
I'm less categorical on this, I see many situations where we would like to warn/debug print rather than fail open.

Perhaps, we could converge on a setting that allow failure while logging it.
