It need to be good enough to be useful, but bad enough for there to be things to be fixed.
Yeah. Many projects that came to Apache was "too good" when it arrived and died.
And it is not for Apache only, across the board.
It is not called Open Sores for no reason. 😉

Stefano Mazzocchi (early Apache leader) once said (~2000); "Only the combination of Great Ideas and Poor Code will generate Great Communities.", as in; if code is "too good", there is nothing for other people to fix and community will not flourish.
From this the "Community over Code" was derived somewhat later, possibly when the Apache Incubator was forming in 2003 or shortly thereafter, and went on to become the most central aspect of Apache Software Foundation.
