Hey, I have opposed this change in the past for two reasons:
Using more than 4 threads doesn't help unless the user is using PhraseDictionaryCompact. See this issue https://github.com/moses-smt/mosesdecoder/issues/39 in fact on most machines you rarely want to run moses on all available threads. Also - threads all picks up virtual (hyper) threads which are in fact harmful to performance. If you want to change the default I think it would be better to have a sane default like 4.. It would boost performance for most people and if you run it on machines with less available cores it would be not too bad.
