@lidel this seems fine. I don't think we're introducing any new problems on the CoreAPI/Node boundary, but wanted to double check. WDYT?

The boundary issues we generally run into are that IIRC accessing the node directly doesn't respect the --offline flag, however I think we may already have that issue given that we use node.PeerHost below.

return err

if isInBlockstore && node.PeerHost != nil {
