Future of D Interface Files?

[Andre via Digitalmars-d]

Hi,

what is the future of D interface files? Somehow they work except for 
new features package.d files or @properties.
I got the information that D interface files shouldn't be used anymore
as this functionality is outdated/broken
(d.D.learn) <lhok7c$2451$1 at digitalmars.com>

On the other side this seems like a big missing base feature of D if I 
cannot create *.lib files and ship the D interface files.
(Closed source, payed lib files...)

Are there plans to make them fully available again in the future?

Kind regards
André
