 developers to use async scripts as dependencies and trusting them to do so
 responsibly fairly convincing. If we can agree there, then we can address
 additional edge cases and nuances.

 sense here (assuming good inline docs).

 I would trigger `_doing_it_wrong()`, but I'm not up to date on what core
 mandates for its usage policy. Other than that, I've found `_d_i_w()` to
 be a very well working education tool.
