TC39 proposal cancellation

[behzad888]

There are any plan for TC39 proposal cancellation?

If not: Based on TC39: user-controlled cancellation of asynchronous operations through the adoption of a set of native platform objects.

At first, we must have need to asynchronous operations as long as we can use cancelling asynchronous operations that cleared and consistent approach as below:

• Asynchronous functions or iterators
• Fetching remote resources (HTTP, I/O, etc.)
• Interacting with background tasks (Web Workers, forked processes, etc.)
• Long-running operations (animations, etc.)

Seems like a good addition once the proposal is more mature.
