well yes JC is not so common these days, but it is because it is just Jack Herrer variant or outcross, which is still around in some form, classic NL, Skunk, Haze mix.

Jack's Cleaner is a strain Subcool made in Fla in the early internet Overgrow years...
It was "the cleaner" x Jack Herer....
The Cleaner was found from seeds from founding Overgrow.com member SKOOSH. The "cleaner" was a purported hybrid of all kinds of random stuff from the 80s. No real clear lineage just what was supposedly in it. Some of those were the ones you listed ((Pluton x Lambs Bread x Purple Haze x Northern lights))
Sub crossed it with Jack Herer seeds he brought back from amsterdam.
Sub had his issues and it was held/preserved by Stony Pony and redistributed back around 2006.
I grew it years ago, but found it to be not as good as a proper Jack Herer pheno. It's a pretty easy plant to grow but has some odd characteristics. The Original Jacks Cleaner clone grow small green seeds in the buds, not from pollination. They never mature, and are like enlarged embryos. If you keep Ca/Nitrate levels high at the end of flower it will also throw some big blaster bananas from the tops. If you mess with those, they can drop pollen. Otherwise, its a stinky pretty plant that one todays concentrate market would likely be popular. As buds, it wasn't particularly due to the little green beans.
