Buildd used to consider alternative build-dependencies, and it caused a never-ending stream of package transition entanglements, because the delay-building-until-installable thing never happened, which meant that every rebuild of something to solve a problem would have to either be timed very well, or would be likely to be playing a roulette game of "will the rebuild solve all problems or create yet even more". -policy: this is a question that has come up before (https://lists.debian.org/debian-devel/2016/12/msg00470.html is another example that springs to mind, but I'm pretty sure there are more), so I think we should document in Policy that a) buildd only looks at the first dependency in alternative build-dependencies, and b) why this is the case. Suggestion: ---8<--- Note that sbuild, the program which builds packages on each of Debian's architectures, only considers the first alternative for any declared element in the Build-Depends: header, after removing alternatives with architecture restrictions that don't apply to the architecture on which the package is building. All other alternatives are ignored by sbuild. This is done so that package dependencies are predictable; previously, sbuild would consider alternative dependencies, but it made binary package dependencies change based on whether a particular package happened to be installable on unstable at the time of a package rebuild. These changes were unpredictable, and made handling transitions harder than they needed to be. --->8--- Not sure in which section to place this though.
