This is why certification is bad, folks.

How bad? In this specific case it is not too annoying but it does limit both freedom of expression as well as business opportunities. On the Xbox 360, indie developers were required to be published by Microsoft and give their console exclusivity or launch date parity. Things are a bit more relaxed on the Xbox One with ID@Xbox permitting self-publish releases. Microsoft will work "on a case-by-case" for games that have already been released on other platforms.

But Australian developer, Witch Beam, is unable to launch on the Xbox One. They had enough resources for a PC release in January followed by PlayStation 4, Vita, and WiiU. They did not have enough manpower to include Xbox One in that second window. As such, unless Microsoft gives them a waiver based on press attention, "Assault Android Cactus" will not appear on the Xbox One.

Microsoft has been improving their policies since the Xbox 360. Still, because of the precedent they set, they can always change their agreements at any time. Retail certification? Yeah, that can be useful for end users. Platform certification? Big problems.
