> NT kernel ABI isn’t even all that stable itself

Can you give an example where a breaking change was introduced in NT kernel ABI?

(One example: hit "Show" on the table header for Win11, then use the form at the top of the page to highlight syscall 8c)

Changes in syscall numbers aren't necessarily breaking changes as you're supposed to use ntdll.dll to call kernel, not direct syscalls.

The syscall numbers change with every release: https://j00ru.vexillium.org/syscalls/nt/64/

Syscall numbers shouldn't be a problem if you link against ntdll.dll.
