emit_unless is very unintuitive and confusing. The first impression is as if it will only emit if the parameter is true, without the altnative "delay as a bug".

emit_unless_delay expresses two things:

  1. emit unless the delay parameter is true
  2. either emit immediately or delay as bug

Not totally happy about the name of the function (though I don't have a better suggestion), but I do think that it should be fixed, so I'm fine with the rename for now. Though I also wish that people would read the docs of the functions they're using 😅
