I agree `Object.assign` looks like the nicest solution, and seeing that
we already use it in our codebase, I'll go for this one.

You're right, `submitOptions` also has the potential for the same class
of bugs. The current usages of `submitOptions` look unproblematic. But
since we go for a more general fix for `extraRequestParams` anyway,
let's handle `submitOptions` similarly.
I'll send a v3 (just noticed I forgot the `v2` in the subject for this
one). Thank you and sterzy for your suggestions!
