Typically only one iterator is present at any time, so it's overkill to devote an entire context for this. Get rid of it and use the caller's context. This is tidy-up work, so no backpatch in this form. However, a hypothetical extension to v17 that tried to start iteration from an attaching backend would result in a crash, so that'll be fixed separately in a way that doesn't change behavior in core.
