I guess not supporting arrays in the initial patch should be fine,

Personally I’d require solving the entire problem before putting any of it in.  This doesn’t seem like a feature that needs two years to implement.  And it isn’t like we don’t have usable tools while we wait.  This is for standards conformance more than anything.
