Both of those things are important, sure. I wanted this post to be talking about the higher level conceptual question, and then using interesting examples to tease out various aspects of that discussion, more than "here's what I think are the biggest differences between the two."
I think these two things are also things people would argue about a lot. It's hard to talk about them in a concrete sense of things, rather than just "I feel like code usually does X".
Right, sorry, I didn't mean to imply that you should have covered stack allocation in your post. I think your post covers the right material to make its point.
This is more of a side comment about a different question, perhaps "ok fine, but then what are the language differences that could be performance-relevant for one language or the other, even if (as you say) they don't lead to a yes/no answer for your original question?"
