The review for SE-0291 Package Collections ran from November 10 to November 18, 2020.
The core team has decided to return this proposal for revision.
During the review, several community members requested to learn more about the Package Collection data format. The core team felt the proposal should be amended to explicitly call out if the data format is part of the feature specification or not, and provide reasoning for its inclusion or exclusion.
For example, it makes sense for the data format to be included if it is considered a stable API that users may build tools around, and conversely it makes sense to exclude if it is considered a non-stable API that users should not be generated directly.
Thank you for your feedback thus far and helping improve the Swift programing language and ecosystem.
