This could be tested for any of our C++ methods.
Maybe it doesn't matter, but the one picked here means this isn't tested in Worker threads.

Yeah, I’d say it doesn’t matter – these things are pretty independent, and I’ve chosen something that is likely to stay a directly C++-backed method for a long time. I’m happy to take other suggestions, though.

Seems like this conflicted with #27224 😄

Nice, but what about @joyeecheung's assertion:
That's why I didn't do it in #26096, I felt like it should be firstly investigated if some modules rely on some methods/functions being constructors. |
@Hakerh400 We can run our ecosystem checking tool on this, but generally, this should be safe to do. None of the methods affected by this are likely to be used as constructors, and I’m not concerned that there could be significant ecosystem usage of this. Plus, this won’t be released until Node 12. |
