Using anything non-serializable for action types is discouraged:
https://redux.js.org/faq/actions#actions

In fact, this is the Flow definition for dispatching actions:

declare export type DispatchAPI<A> = (action: A) => A;
declare export type Dispatch<A: { type: $Subtype<string> }> = DispatchAPI<A>;

Note how the `type` field is defined as a subtype of string, which Symbol isn’t.

BaseApp does all the heavy-lifting related to creating the redux store,
navigation, and so on.

App currently handles URL props and actually triggering navigation based on
them.

This commit adds a state getter that considers checking the enabled/disabled state of the calendar feature, so then other features don’t have to do it manually.

Knowledge is power, man!

We moved "knownDomains" from calendar-sync to base/known-domains.
However, we do have an official release in the app stores and I'd like
us to not throw away the knowledge it has acquired.
