They cited code style and porting as reasons to use go over c#, not performance.
But I just said my point is not about performance at all! It is about the whole package. Performance of c# and go are both enough for my usecase, same for java and c obviously. They just told us that they don't think the whole package makes sense, and disowned the AOT compilation.
Which made me naturally think your point was, indeed, about performance. Although as it appears to be, I'm wrong, so it's fair enough.
