I don't think there are enough eyes at this point for a strict review
policy. How many of the current packages have any maintainer? Who was
maintaining the stats package before Josef got involved? How many folks
besides Robert could look over the changes usefully? How many folks looked
over Travis' recent addition to optimize? Who is working on the
I think at this point we would be better off trying to recruit at least one
person to "own" each package. For new packages that is usually the person
who committed it but we also need ownership of older packages. Someone with
a personal stake in a package is likely to do more for quality assurance at
this point than any amount of required review.
I don't have a problem with folks complaining about missing tests, etc., but
I worry that if we put too many review steps into the submission path there
won't be enough people to make it work.
