I think the browser is indeed a good analogy.

If we have malformed HTML or even worse issues like e.g. a failed CSS
include, then yes, we expect the browser to render as much and as nice
as possible. But what LilyPond currently does is displaying a big modal
over the page saying "I'm sorry but I couldn't render the page due to a
fatal error. Please click here to close this message and view the page."
