Well, NVME drives better get unproblematic real quick, its not like they are going away you know. Look at any PC gaming enthusiast PC, and you often times don't even find SATA drives in them anymore! They will have usually 1 or 2 NVME drives directly mounted to the motherboard, this is common practice.
If there is any type of driving that is going to be going away soon, it will be SATA drives. The 2.5" drive has been great and all, but with companies trying to make things smaller and cleaner, you have to make a sacraphice somehwere.

See that? M.2230 Look how small it is! Well, give it a couple more years, and you will see notebooks coming with these things as standard.
