It is about time. I know WraithX submitted his code to them years ago. IIRC it is a slower than mine, though in a nice neat library. I'd like to see either a standard Selfridge strong Lucas test,...

Good point. The sources don't even include a range for a in the theorems so they side-step it that way. Only when one has to actually go implement something to *find* a suitable value does this...
