Official compiler

[Márcio Martins via Digitalmars-d]

I was reading the other thread "Speed kills" and was wondering if 
there is any practical reason why DMD is the official compiler?

Currently, newcomers come expecting their algorithm from rosetta 
code to run faster in D than their current language, but then it 
seems like it's actually slower. What gives?

Very often the typical answer from this community is generally 
"did you use LDC/GDC?".

Wouldn't it be a better newcomer experience if the official 
compiler was either LDC or GDC?
For us current users it really doesn't matter what is labelled 
official, we pick what serves us best, but for a newcomer, the 
word official surely carries a lot of weight, doesn't it?

 From a marketing point of view, is it better for D as a language 
that first-timers try the bleeding-edge, latest language features 
with DMD, or that their expectations of efficient native code are 
not broken?

Apologies if this has been discussed before...
