Any way to --dump all recipes also for recipes not supported on platform via e.g. [windows]

Hello,

is there any way to do `just --dump --dump-format` and see all recipes like:

```
[linux]
linux-command:
...

[windows]
windows-command:
...
```

would give:
```
"recipes": {
"linux-command": ...,
"windows-command": ...
}
```
Also would it be possible to do:

```
[linux]
x:

[windows]
x:
```

I know it can be done but I am unsure if this can be presented in json without breaking backwards compatibility.
