Sorry, but I don't see the benefit compared to the "is 90% green" solution.

>> 2) When we still want the CoreBuilder concept: Can we make the core/non-core transition without any SVN change? What about improving the buildbot-master, so that it dertiminates the core/non-core on the fly, by checking the last x builds? I don't like the idea of adding and removing the the bots to the "core list" all the time.

An alternative might be to split the bots into categories like "apple", "chrome", "qt" and so on instead of "core"/"non-core". But this won't help in catching problems on the "other" bots. So not sure if that is a practicable solution.

I have no idea about a general working rule, but as of my experience the committer simply "don't see" the problem. E.g. WinCE bot builds the interpreter version of JSC, which is a "core feature" and not port specific, but the commit author didn't see the break.

I don't want other folks to do "my work", I'm not happy, but ok with the current state. I wanted to add my view to this topic. :-) Maybe other folks have similar requirements, so that we find a more general solution, instead of many home brew ones.
