Add workspace_idx to niri msg -j windows output

[itshog]

I'm trying to script a window switcher for Niri with a dmenu-like program, and I'd like to display the workspace index (the one shown by waybar, which appears as idx in the output of niri msg -j workspaces) next to the window title. I get the needed information by parsing the output of niri msg -j windows, but the idx is missing: I know that I can use another command, like niri msg -j workspaces | jq '.[] | select(.id == $my_id) | .idx', but I'm wondering why it wasn't included in the first place.

Workspace idx is part of workspace-specific data, why should it be included on the window? That would require sending window update events for all windows down whenever an unrelated workspace disappears or is reordered.

Thanks, I didn't take into account the different nature of workspace_id and idx. I think this should be closed now.
