Maybe those are outdated n

..
I do not have any doubts,. It will be back.
It may be back before any alternative method is ready to be deployed.
As it looks for the alternative method being developed like they need some more development & testing time for something like that as that is not a rushed type of release, but alternative are good they would of been helpful the past few months no doubt
but alternative might be on the back burner quickly as a secondary option.
but is a useful option to have around if succeeds but they still have not lined up all the test candidates yet
So there is more development likely when other models are tested and potential issues may be found., in other words there is likely alot more work to be done before it ready for user's in regards to the Alternative method. . However its hard to judge something we have only seen a screen of to this point. So who knows it might be the foundation for something great.
I do not know when the toolset will be opened again, but i believe we will see it online sooner then later.
