Get accessor in props about jsx

[QbDesu]

Let's review the technical requirements that would be necessary to implement such a feature:
In order for this to work intrinsics <a href=${this.b}> as well as components <MyComponent someProp=${this.b}> it would require passing the props as a proxy with overridden get accessors for the prop in question.
Not to mention a couple of things would break. What would cause the child component to rerender if the value changes? Implications for the lifecycle of the child,.. etc.
