Or name="show_comment_errors" or something like that.

We'd have to pass the error through the query string anyway, so
comment_error_message() could just do get_query_var('comment_error'),
echo it if it exists, or output the hidden input if not.

Not as much as you might think. From a theme designer's point of view,
all that's required is adding a comment_error_message() function to
their comment form. The only inelegance comes from the hidden input
and the forking that would be necessary in wp-comments-post.php to
check whether the hidden input was there, both of which are required
for backward compatability.
