I personally agree. But the default expectation (and therefore the design) should follow the practices of the language. If JS allows mutations on the objects passed to a function to be reflected on the parent, I believe frameworks should follow this paradigm.
And in the end in Gea developers have full control over this, just in the same way they do in real life. `child({ ...obj })` easily solves this, for example, in both idiomatic JS and in Gea.
