Related to this it has been suggested to me that we could setup a bidding/kickstarter style campaign for different platform or arch support. If people are interested we could estimate what it would take to support builds on extra arch/platform combinations for the duration of a release. And if there is enough community support to fund the project we can turn on specific architectures.
Also we are currently building i386 and amd64, we could consider dropping i386 on some platforms to save resources.
Please take a look at the results of both surveys and the above proposal and give your feedback.
