There's room for some DRY here if we want to - but for the first pass I chose to just add this hook here and change in place. eventually we could do something like useSubmitImpl(getRouterOpts, fetcherKey, fetcherRouteId) where getRouterOpts would be the DOM-aware way to gather a submission and the memory version would pass a simple non-DOM-aware implementation.
But it makes the types tricky since the returned SubmitFunction function types are then dependent on the getRouterOpts implementation, so it doesn't feel like that would be quite the right abstraction.

Found this little nuanced bug when copying over the fetcher tests. We need to proxy along any fetchers returned from handleLoaders through to completeNavigation so we get a new state.fetchers instance via the subscribers. Wasn't exposing any user-facing issues though since users can't depend directly on the fetchers map and the internal state.fetchers.get() was always properly updated.

On hold until #10413 is merged. This will likely be easiest to just re-do since the changes I think will simplify this a bit. |

Closing for now |
Now that #10324 is handled, we can support
useSubmit(and thereforeuseFetcher) inreact-routersince those are no longer coupled toDOM/<form>/FormDataavailability.
