Is facebook moving away from D?

[Bruce Adams via Digitalmars-d]

I was just looking at the git hub pages for warp and flint and I 
notice they've recently been labelled as "no longer maintained"

https://github.com/facebookarchive/warp
https://github.com/facebookarchive/flint

Now I could imagine that warp could be considered complete as the 
C/C++ preprocessor doesn't change very often.

Flint could perhaps be replaced by something equilavent to the 
C++ core guidelines

https://github.com/isocpp/CppCoreGuidelines

But adding a comment that the projects are no longer maintained 
(presumably by a facebook employee) suggests an internal move 
away from D.
It also invites speculation about either the cause or the effect 
of Andrei's move to the D foundation.

Though this is of course jumping to conclusions based on very 
little information.

What do you guys think?
