This should eventually have the same meaning as it does for the modules language under the ephemeral_values language experiment, but as of this commit is just accepted during decoding and then ignored. The rest of the functionality will follow in subsequent commits. There's no specific experiment guard in this case because the stack configuration language is already experimental as a whole anyway.
