Sure you can write your own cancellation framework.
That can be done quite easily in C too.

The point of standardizing a particular cancellation framework
is to enable interoperability between code written by different parties.
For example, this is needed to allow application code to cancel threads
which happen to be running third-party library code, or even standard
library code such as getchar() or system calls such as read().
