Whats holding ~100% D GUI back?

[aberba]

There's been attempts to implement a native D GUI toolkit but it 
seems none gets community attention. The closets...DlangUI 
(https://code.dlang.org/packages/dlangui)... seems no more under 
active development...getting to a year now.

Ketmar and others have been in the talks about doing something 
towards that. Whats happening now? What's holding 100% D GUI back?
