That wasn't the intention. It probably wasn't written out since the full semantics isn't spelled out yet (though Sam and I have been making good progress working through the details of the semantics), but the idea was that the properties of the options object are read in up-front and stored internally. The getter always returns that internally closed-over value that was obtained when the loader was first created.

The initial value. We can look into what it would mean to make it modifiable, but we'd probably not make that the API; we'd probably just have a setter.
