Would it be valuable to include specifying that the entire rest of the free will galaxy and all within it be healed, among the group of existing types of clients in the Lightworker Healing Protocol? In addition to reaching, potentially, many other victims like humanity, this would widen the purview to net many additional spirit meddlers attached to other beings and speed the day when they have all been sent to the light for cleansing and rehabilitation. Are there other potential advantages?

This is another fine idea for the reasons you have stated. You are aware of the considerations here but there is an interpenetration of the energies. There are not arbitrary walls separating your solar system from the rest of the galaxy. So the many energies of consciousness and spirits out and about can freely come and go across the galaxy and there will be an influx of new spirit meddlers from distant areas to the extent they are removed from the proximity to the living human community by your efforts. There is a relentless and growing desperation to have sources of energy as so many soul beings are taken, and there will often be a wide-ranging search for fresh blood, so to speak, so humans will continue to be at risk as long as these spirits abound within your galaxy as a whole. There are many lost soul spirits of extraterrestrials as well as humans that stray beyond the solar system environs. To fully heal these communities of beings needs a very broad outreach for their rescue. This is technically allowed with the current Protocol, but this broadening to make it all‑encompassing will add greater latitude and prioritization for the broadest possible purview with the rescue efforts. In a sense, it encompasses everything else spelled out by the Protocol, but it would still be advantageous to have the individual classes of target clients stated explicitly for greatest possible clarity, so the human intention of the practitioners will be in alignment with the best intentions of the Protocol, and things will not get overlooked because the person has not been fully educated about the potential reach of the Protocol, so including this as an extra category will only add and not take away.
