Everyone I know is excited for the new Google Search Console Beta to be released to them, there is some added reporting functionality that more and more want to see. But not everyone has access to it yet.

Here is how John Mueller responded to that question on Twitter:
If people like the data, sooner or later we'll probably include it in an API, but ... ¯\_(ツ)_/¯
