> You don't need to write platform-specific code if you use some cross-platform framework. For simple programs it may be enough to use only the standard library of your language of choice.

That's a circular argument and "some" is doing a lot of work there. What cross-platform framework would you be referring to?

> It has little value. Compiling a separate binary for each OS isn't that hard, since only a handful of architectures and operating systems are actually in use. Using an abstract cross-platform binary (like WASM) in the other hand adds extra performance costs and other user-side overhead, which isn't strictly necessary.

It my have little value to you but that doesn't mean it has little value to everyone. I don't agree that compiling to multiple architectures is without difficulty and restricting yourself to only popular ones proves the point. What specific "other user-side overhead" would you be referring to? Lots of things aren't strictly necessary, that doesn't imply they're not necessary. Yes, there is a performance cost. Sometimes that cost is worth paying.
