Yes. Without reservation. You need to enable NVMe in the kernel, and
there is a user-level program for doing things to them (like checking
number of reads/writes). There is no great problem setting up a boot
loader, any more than for any other sort of drive.

I've had a pair of Samsung 500Gb nvmes in RAID-1 in my 4 year old
machine since it was new. As yet I've had no problems with them. In
fact, the machine has never known spinning rust.

If you've got something to fall back onto, yes.

I can't comment at all on that. I built my machine from components.
The only slightly tricky bit was finding a PCIe card to hold the second
NVMe drive.
