Oh wow, I'm a JetBrains fan, but didn't know about this - if it delivers in the same way as the remote extensions for VSCode, it's going to be great!
Have you tried the Projector beta yet?
I have. It's very impressive but not ready for daily use IMO. (I tested it with IntelliJ).
However, the 2012.1 releases now support running code on via WSL2 or SSH, which is closer to VS Code's setup. https://blog.jetbrains.com/idea/2021/02/intellij-idea-2021-1...
It's still beta so they have a lot of work to do.
