Is “little turnover” being used as a euphemism there? There was little turnover because for years, the 4 people on the team were not even allowing anyone else to apply to join the team. The team was obviously undersized, which is further confirmed by a need for even more members after replacing 1 member with 6 new members. Unfortunately, WordPress doesn’t yet have a governance structure that can address problematic behavior, like has occurred with this team in a timely manner, and instead it took a decade for a change.

Hopefully, the new members of the team will make changes to avoid the problematic behavior of the team up until this point. A good start would be to be more transparent in the reviews of new plugins, similar to what the theme team already does, https://themes.trac.wordpress.org/. In the past, it was pretty clear that some of the reviews were not really happening, but there was no way to see who was supposed to have done the reviews that appeared to have not happened.

The new team members don’t look to have much security expertise, so it would be great if they would reach out to the WordPress security community to work with them to address some of the security problems the team up until this point has refused to work with others to address.
