The point is that it's clearly not just a less maintained, less tested implementation. It's 1.61x faster for one in real world apps, in some case even almost 4x faster.
I am curious why it's faster. Golang isn't that much slower than Rust, aside from the garbage collector. 4x performance improvements is much bigger than what I expected.
If that was your point, why did you spend a whole paragraph saying "teach us? What a perverse question."
The comment I responded on put forth a generic argument that implied if we can not learn from it it has no value. That is what I was responding to.
