Can a request for pooling energy of requests for human betterment through the Lightworker Healing Protocol, be extended to ask that the energy of all prayers for benefiting humanity be added onto all Lightworker Healing Protocol session requests? Will that be disallowed because the people praying are not asking for Protocol sessions specifically?

This too must be disallowed, and not just because they are not envisioning Protocol sessions as a way of implementing their prayer request. It is because the prayer is to the divine realm, and not to you, to have the changes brought about. So anything that is done to apply prayer requests launched in a general way for human betterment through Protocol work of actual practitioners must be done by divine realm and, in fact, can be done. This is one prerogative of the divine realm, to implement a prayer request in a way that is most suitable for the particular circumstances involved—the standing of the person launching the prayer with regard to their belief quotient, their belief in themselves to receive a divine audience and actions on their behalf, and so on. So given the wide array of individual circumstances of general prayer requests of this kind, the aggregate of the whole does provide considerable energy and the divine realm can, by virtue of its mandate and the non-specificity of the prayer request, have some latitude as to how the divine realm may dispense the energies in question. So you need not worry about this or take this on as your obligation or opportunity. If appropriate, the divine realm will factor this in as your sessions are worked on.
