Don't optimize for minimum hate, optimize for actionable feedback and ignore the haters. Easier said than done, though.

Remember you don't need comment trolls on your team, and you'll go insane taking them seriously. Focus on piquing the interest of motivated language nerds. I personally would have really appreciated a "look, were still 10x (or whatever) slower than Python, so now I need all the help I can get working on the codegen, etc." This would have given me quick perspective on why this milestone is meaningful.
