I'd argue that the former is less important than the latter, and my understanding is that Visual Studio is still the IDE for Windows-centric development, so for those MS-first developers, Rust missing from VS means Rust is poorly supported, end of story.
WSL is really nice, as is Windows Terminal. I particularly love its fonts (but that's probably just me).
The alternative being macOS, if Apple actually had competitive prices for all kinds of world economies.
If they can replicate that capability, I think it can be a draw.
I was a mac / Linux guy before my current gig, but Visual Studio is so much more capable than XCode that I basically only use the Windows machine except to debug mac-specific issues. Less so, now, admittedly, that the malware scanner process is literally always pegging a CPU core.
That's an excuse, not the reason.
IntelliJ RustRover has been around for years.
Similarly, VS Code has had Rust plugins written by the community in their spare time years ago.
Because of coding agents? :D
