Thanks a lot for this contribution @jopemachine!

We might want to name this option signal instead of abortSignal to match the name currently used by child_process.spawn().

More fundamentally, I am wondering whether the core signal option should just be used instead? I have written some potential ideas in the issue, please let me know what you think.

Thanks for pointing it out, I just updated the option.

Should I delete this document too? or should I mark the cancel method as deprecated?

I believe we can directly delete that section of the documentation, good catch! 👍

Thanks again for this PR @jopemachine! There are a couple of things I have noted. The tests look great! (But the CI tests are currently failing)

I appreciate your detailed feedback :)
I tried to reflect on all the feedback as much as I can.
If I'm missing something or got something wrong, I appreciate your letting me know.
