Is this something the distribution maintainers are supposed to track? Let's say package x is available on Debian and decisions is available on the raspberry pi. The package maintainers on Debian side are the people who compile and ship the binaries for raspberry pi, no? Are the authors involved in this at all? Or is it that the package maintainers take a more handsfree approach and only build on platforms that the authors have said the software works on?
