If you had designed the early web browsers, the web never would have
caught on, as indeed many other networked hypertext systems predating
the Web did not; being liberal in what you accept is a crucial
principle in building decentralized systems, and its embodiment in the
Web made the Web possible.

Having "bad HTML" warnings is, of course, extremely helpful.  It makes
it possible to be conservative in what you send.
