No, it isn't about "does this look good or not", this is about not having a big ugly error if you have a tiny error somewhere. It's not about a page with bad layout because of invalid CSS, it's about Mozilla's own big, ugly error message. Your visitor will not see anything but the error message.
And to be fair, it is often hard, if not impossible to iron out all bugs before a site is released, especially if you have to check every single piece of data being entered, whether it is in some sort of CMS, or data from an external site, or perhaps (in case of blogs (okay, I said non-personal earlier, but hey)) trackbacks/etc.
I had two points:
You want a browser to be at least a tiny bit forgiving, not much, just a little.
You don't want to use an XHTML which is being sent as application/xhtml+xml for business sites. And if you're sending it as text/html you might as well use HTML 4.01.
Have you seen how Mozilla shows an error in a XHTML document sent as application/xhtml+xml? It shows something like "character not escaped on line X". Totally unforgiving. And at the same time an excellent reason not to use XHTML for any non-personal webpage.
If you have a website, you want people to see it, even if something went wrong with creating a page.

Yes, but unlike webpages, C++ code will only be written by developers.
