Please, clarify official stock

Yes, thanks...but...in reality I'm not interested on their inner bussiness. I only want to have some customer "security". For instance:

*How can we be sure boards which were deprecated due to several reasons won't be deprecated again (Due, Leonardo, Yún, Esplora, etc) and the same for shields (GSM, USB Host, etc, etc -please, remove these very outdated and space-wasting Tinkerkit connectors from Motor shield!-, the LCD, etc, etc)?

*How can be sure the level of software support will be correct (for instance, what's going on with Wifi/Wifi 101 shield libraries?; what's going on with outdated USB Host library and some more?, what's going on with Yun system?...) Even Arduino Ethernet 2 now hasn't a decent library, and so on.

Ohh, how dizzy it's all

Thanks all of you
