Module status_bar 

The strip along the bottom of a window.

A status bar is where a desktop tool says what is true right now: which branch, how many problems, whether the indexer is still running. Every one of those facts belongs to the host. The bar draws what it is given and invents nothing — an item with no state carries no state, rather than a reassuring green dot nobody asked for.

Stale is not current

AsyncValue already separates a value from what is happening to it, which is what lets a failed refresh keep the last verified number on screen. StatusItem::tracking reads that vocabulary straight: a value whose status is Refreshing or Error while a value is still held is drawn with its last verified text and the word stale beside it, and publishes stale as its value. It is never drawn as current.
