No, the whole point is to eliminate dependencies that they have to maintain. "not obligate" really doesn't mean anything if it's available as a backend--the obligation is on the Zig developers to keep it working, and they want to eliminate that obligation.

And the original question was "how will they reivent the wheel on the man-years of optimization work went into LLVM to their own compiler infrastructure?" -- the answer is that Andrew naively believes that they can recreate comparable optimization.

There are a whole lot of misstatements about Zig and other matters in the comments here by people who don't have much knowledge about what they are talking about--much of the discussion of using low-level vs high-level languages for writing compilers is nonsense. And one person wrote of "Zig and D" as if those languages are comparable, when D is at least as high level as C++, which it was intended to replace.
