Taking a quick look while scanning PRs, I'm wondering why details like enableInContextSidebar and recaptchaToken are bleeding into the postComment method signature. I realize only one of these are added here, but this don't feel appropriate to me.

Hi @e0d,
Spam posts, comments, and responses have been appearing on the forum due to bots, so we've temporarily added a CAPTCHA to prevent this.
The enableInContextSidebar flag is used for event tracking on the backend.
