My point is that the "it's harder" is why syntax is the differentiator.
The idea that syntax isn't a huge differentiator for languages is insane to me. Yes, small syntactic changes like "fun" vs "fn" may not matter overall, but obviously people choose languages based on what they can easily express by typing sourcecode.
Arguably, the difference between await syntaxes is closer to "fn vs fun" than "lazy vs strict", but I think that there's a lot of context that pushes it closer to the latter (we're talking about how a fundamental control flow primitive is implemented, and this will impact future control flow primitives).
