And I wouldn't say that's a widely held definition. For example:
> The red line, or "to cross the red line", is a phrase used worldwide to mean a figurative point of no return or line in the sand, or "the fastest, farthest, or highest point or degree considered safe." [0]
If adopting these practices means they stick around and people will always argue for bringing them back if we stop... We've crossed the point of no return.
