There is no "what we'd like them to do" -- we have no policy or preference or anything as a group. Everybody's just guessing what other people want and care about, and then sometimes we're all grumpy at each other.
This is a great point. Many years ago I had some spare hardware and wanted to setup a build animal. I looked through the list to see what unique permutation I could provide, but it was a very manual process! It would be nice to at least have a list of "wanted" configurations.
Perhaps a summary of the currently running configurations. So you could see, for example, which compiler versions were run in the last week, and perhaps how many animals were running it. Basically, some meta information about the current runs, which could help us drive the "wanted" list.
