Unnecessary

Unused or unnecessary code.

Diagnostics with this tag are rendered faded out. The amount of fading is controlled by the "editorUnnecessaryCode.opacity" theme color. For example, "editorUnnecessaryCode.opacity": "#000000c0" will render the code with 75% opacity. For high contrast themes, use the "editorUnnecessaryCode.border" theme color to underline unnecessary code instead of fading it out.
