"I'd also like to say NVMe is mind blowingly fast on the desktop I've got and something sorely lacking from Apple's offering adding another downside to the current Mac desktops."

I see that folks are putting nvme cards into their older mac pros:

Is there a recipe that allows one to boot from an nvme add-in card on an older mac pro ? (in my case, early 2009)

I would suggest this card, it should work, it is SATA based as opposed to NVMe. I have installed a few of these in on several older systems (x58 based and others) and saw a very large performance bump, even versus SSDs connected via aftermarket PCIE SATA-3 controller (running at 500-550mbs). YMMV if attempting to clone an existing drive - I have had this problem with add-in PCIE cards, older motherboards, and various operating systems - a fresh install to one of these drives will likely be easier.

I don't think so, the Mac Pro's firmware doesn't understand NVME, you'd need to use an ACHI based M2 SSD with the PCIe card. (so many acronyms!)
