Just to preface what I'm about to say: I don't know what the developers would say about adding this feature. I did some digging and couldn't find any mention of this specific feature. I'm just going to make an educated guess based on what I've seen developers say in the issue tracker and elsewhere.
Anyway, with that said, I don't think they'd be against it, but won't take the time to implement it themselves as they're busy with other things. However, if a developer that has contributed to the project before or another active community member writes their own well thought out implementation, it might be considered.
Adding a feature isn't a one-time thing. The code needs to be maintained as related upstream code is changed.
Ideally, Google should add this feature so everyone can benefit.
