What you're saying sounds to me a bit like one can break community rules if mods won't notice right away. If community rules were broken, I don't think it matters much if it happened right now or earlier. Besides, I would also expect that someone breaking the rules will not argue in good faith.
So, to me this example doesn't prove what you imply.
For me, type system is the most important feature for a programming language to be pleasant to use. It's very nice to see that Rust doesn't stop on what it already has, which is already pretty good, imo.
