You've tested with every single user agent, in every single
environment that your users have? That's impressive.

How do you propose to identify the error recovery capabilities of the
many user agents out there? How about the ones which have not been
written yet?

The purpose of having a standard is to have a common frame of
reference for authors of webpages and authors of user
agents. Validation is a means of ensuring that your code follows that
standard (to the extent that can be expressed by a DTD in the case of
markup). If some, or even many, user agents are capable of dealing
with errors then that is lucky for the author (who fails to undertake
basic quality assurance) who makes a mistake when writing their
page. Its not a good reason to deviate from the standard since other
user agents may not perform the same degree of error recovery.
