The “No new launch vehicles” adage reads to me as “Don’t develop a new browser when you make a website”

That doesn’t mean we never need or want a new browser. It just means that developing a browser is a separate project and if your fancy websites requires a new browser, it is in fact a browser development project, not a website project.

I take it as similar to the “never do a massive rewrite” rule for coding. It’s not that it never should be done, it’s that it shouldn’t ever be assumed to be “the easy part”.
