npm logout command leaves associated scope

[joedragons]

I ran an npm login command as follows:
npm login --registry=http://localhost:8081/repository/npmhosted/ --scope=test

and these lines were added to my .npmrc:
//localhost:8081/repository/npmhosted/:_authToken=33524559-18c1-3590-bf4e-8336a6418edb
@test:registry=http://localhost:8081/repository/npmhosted/

On npm logouts, I was unable to get the @test scope to remove.
I tried npm login --registry=http://localhost:8081/repository/npmhosted/ --scope=test, npm logout --registry=http://localhost:8081/repository/npmhosted/ and npm logout --scope=test

Is this intentional?
It seems like undone cleanup that I subsequent have to do manually.
