Sure , but that all those years of work are not of creating new stuff, there is a lot of work on just modifying existing code and not breaking stuff. You do not need to get all Linux features at start, I would focus on the server stuff, support the popular server hardware and popular server work so filesystems and networking. I would hope some competent developers would write a new kernel from scratch then getting 10% of some Linux rustiffied. When you edit shit you need to make sure not break shit, so you are limited, you move slow and you have to implement backwards compatibility. Amazon,Google,Facebook could work on this if they care for security but probably using VMs is cheaper for them.
