So... how's the code up there?

I suppose I can at least ask, as the new update came out and all.

Is it safe to return with my helicopter projects; or is the spaghetti monster still lurking in the bowels of KSP? Are things still run entirely through side effects on black box methods with all the real bits hidden behind private flags; or is the code base actually organized into something that won't give me nightmares? Has anyone on the team figured out how to use interfaces instead of constant breaking changes with every minor patch? Is it at all practical to completely replace a stock module without breaking the EULA? Not really expecting any good news, but I thought it was at least worth asking.
