WriteStream (Receive-Job) output cannot be redirected

Do you want to request a feature or report a bug?
Bug

What is the current behavior?
Receive-Job uses WriteStream writes streams (warning, error, etc) directly tot he $host.

Redirect (e.g. *>&1) and Common Params -WarningVariable foo do not seem to function as expected.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

Redirection

Start-RSJob -ScriptBlock { write-warning 'warning'; write-error 'error' } | Wait-RSJob |
Receive-RSJob *>&1
WARNING: warning
error

Common Params

Start-RSJob -ScriptBlock { write-warning 'warning'; write-error 'error' } | Wait-RSJob |
Receive-RSJob -WarningVariable wv; $wv
WARNING: warning
error

What is the expected behavior?
Some manner to capture warning/error output streams (e.g. for logging)

Which versions of Powershell and which OS are affected by this issue? Did this work in previous versions of our scripts?
v5.1 Windows
PsRsJob 1.7.3.9

Any scope for re-direction?
