So in 3 years they broke and re-fixed the dashboard, and added optional signed executables? That sounds like hardly any breakage at all...? Honestly curious, I'm very new to this Mac thing.
(A question: I see people going nuts over signed executables but I've downloaded Gimp, MacVim, GnuBG, Sublime Editor, lots of homebrew tools, and tons of other open source apps to my Mountain Lion machine with zero trouble. Where do the signed executable restrictions get in the way?)
