Sounds like a clean change ... but my question is what is calling delete on asyncResource ?

Without delete we might have a memory leak.

Are you 100% sure that the new NAN APIs and node 12 won't take care of it ? do you have some sort of setup to run some tests....or at least tell me how to do it ?

You could test it by running the code in debug mode and with valgrind to check for memory leaks.

The replacement is safe and it is strongly advised according the new https://github.com/nodejs/nan APIs
