These folks have nothing new to innovate here. The memory manager and VM gets revamped every other release. Exports get broken, binary only module compatibility busted every rev of the kernel. I spend weeks on each kernel fixing the breakage. These people don't get it, don't care, and to be honest, you are wasting your time here trying to convince them. It's never stable because they don't want it to be. This is how they maintain control
of this code. I have apps written for Windows in 1990 and 1998 that still run on Windows XP today. Linux has no such concept of
backwards compatiblity. Every company who has embraced it outside of hardware based solutions is dying or has died. IBM is secretly
forking it as we speak and using it to get out of paying for Unix licenses.
As annoying as it is, accept it and live with it. These people have no sense of loyalty to you or your customers. They don't even care about each other.
