How can a Gated Check-in be configured in tfs 2015 "vNext" builds?

Question

The new build system is pretty exciting. But...

I would like to know if there's any way to create a build definition with a gated checkin using TFS Version Control like it's available in XAML build definition?

Is it a hidden option or difficult to find? If not, is it possible to develop an extension to do that or must we wait for MS to support it?

Not currently, this is currently scheduled for Q4 2015 for vso and in Update 2 for TFS on prem.

Update 03/02/2016: this has been pushed back to Q1 2016 for vso but still in Update 2 for TFS on prem (which I would assume is also pushed back).

Update 31/03/2016: In Update 2, released 30th March, gated checkin support for TFVC was shipped.

This now shows on the Triggers tab of a build definition:
