I would think it was moved off the supported list as the 0.5.2 code base is not be considered stable enough to be warranted as supported.
The SilverStripe core team will continue to work away at the module, Namely halkyon / sean who has done some great work in overseeing it. There is also a few community devs looking into ecommerce - http://groups.google.com/group/silverstripe-ecommerce. Its a large beast but with the help of everyone we can see a few more regular updates to the module.
