My two cents on what D needs to be more successful...

Ok, I agree with what you say.

Indeed, it sounds logical to suppose that the developers of the 
best libraries in each domain won't probably accept that their 
work is adapted to be promoted to the status of standard 
libraries, just to keep the full control on them.

That's sad, because I still consider that D's popularity could 
improve a lot if it was also equipped "by default" to be a rapid 
application development environment for cross-platform connected 
web/desktop/mobile applications, but now I've clearly understood 
why this will never happen.
