I wouldn't say it's "desireable" condition, but it's certainly a normal one. Just about every modern engine runs on the edge of knock under certain conditions because that gives the best fuel economy. And knock isn't an all-or-nothing thing. There are degrees of severity.
'on the edge of knock' and 'knocking' are not the same thing. if you're engine is knocking, something is wrong.
