With three first preference votes for A and five first preference votes for C, the outcome is no longer in doubt. Therefore, using its powers under constitution 6.1.5, the Technical Committee issues the following advice:
1. It is not a bug of any severity for a package with a non-native version number to use a native source package format. 2. Thus, we think that dpkg shouldn't issue warnings, or otherwise complain, when a non-native version number is used w/ 3.0 (native). 3. We suggest that the wontfix tag on #737634 be reconsidered. 4. We believe that there are indeed circumstances in which 1.0-with-diff is the best choice for a particular source package, including, but not limited to, git-first packaging workflows. However, we recommend discontinuing use of 1.0-with-diff in other circumstances, to simplify the contents of the archive. This is because there is currently no other source format which is such that avoid both (i) uploading the whole source, including upstream, for every upload; and (ii) having to maintain debian/patches/ inside the package tree. 5. We decline to comment on the recent source package format MBF. -- Sean Whitton
