and you've missed the last part of that paragraph where I mention unhandledRejection events becoming a defacto standard which straddles a nice line between avoiding false positives (error listener attached latter in the program) and errors going into a black hole

Not sure if that's gone in yet so I've continued using Bluebird for my stuff. You can(and should!) create a global handler for unhandled rejections. It's almost always a bad sign if you get one.

Then don't call them "a bit of a footgun". It's a huge issue, in the process of being maybe fixed, and underplaying it to argue your side does not help matters.

Its already fixed. Thats why it was just "a bit" of a footgun i.e. not unfixable.
