We'd have to decide if we are really committed to USD or not. In the past there was some discussion that the charter is really stable value and if USD deteriorated sufficiently we could switch to something else like a basket of commodities (I'd argue it should still programmatically inflate modestly, say 2%/y). In that case putting too much 'USD' in the name wouldn't make sense.

But on the other hand we could fully commit to USD and if USD really went bad we could create another coin (significant/infeasible development effort to do today at base level, but maybe someday).

On the other hand, I guess if the target changed the name could change again too.
