This makes me think of another reason of Rust in web space. It is that Rust rather explicitly tried to create an image of real hardcore language used for serious systems stuff. And it is of course true in technical sense. In larger context however message became more of like if I use Rust my stuff will become serious.
So now if someone is told their web app is cute little thing more suited for Rails/PHP/Go etc. they will feel patronized and try to use Rust despite being unsuitable because their app is going to be serious one.
I had someone reach out to try to hire me last year to build a website. A neat and useful one, but a website. And they had decided they wanted to use Rust, so they got in touch with me. This person was primarily non-technical, but an entrepreneur. I couldn't understand the decision making that led them there, other than: people had told him that Rust was the new good thing. So that's what he wanted.
