Mike, some will remove the larger leaves when grafting or rooting cuttings so that the energy is directed to the graft or calloused end to form roots. Generally speaking, even if you leave all the leaves on, many or most of them will yellow and fall off anyway. When I am rooting a plumeria or grafting (just started trying my hand at this 4 weeks ago), I remove all the leaves but those small ones right at the tip. Another thing you will see is that when shipping plumeria, many of the sellers will remove most of the large leaves and I have received some cuttings where the leaves were cut in half. I have never seen the need to do either. I just leave all the leaves on when I ship plants. If some of them fall off during shipment or later while rooting the cutting, well, that's just Mother Nature at work. Just my opinions here, you understand. I am certainly no expert, just a hobbyist grower.
and let other people bring up your offspring 
to ATP.
Beautiful!
