Why these extra variables instead of just:

this.sendTrailers(this[kResponse][kTrailers]);

?

Can you add a test for this?

FWIW I don't think it's possible to test this without exporting the kProxySocket symbol. Although
since it's in internal, it's probably ok to do so.

👍 to exporting in the internal module.

I will land this once done and create a test myself in a separate PR.
