I find that Windows developers seem more comfortable with GUI-heaviness in their dev environment, Linux developers seem less comfortable with it, and Mac is in kind of an odd gray zone in between. This seems fitting for the general style of the OS - sometimes sacrificing power to make things "just work" in a minimal UI.

There might be cases where I would find it useful but overall its usefulness is subjective and dependent on what you're looking for in your workflow/workspace.
