Sourceforge projects

[Vitaly Livshic]

Hi, everyone.

I develop small library for D language and attempt to publish it 
on code.dlang.org. Originally, sourceforge project was created. 
However, when I tried to publish it site show error's message:

Please enter a valid project URL or tuple to a GitHub, GitLab or 
BitBucket project, such as https://gitlab.com/dlang/dub or 
bitbucket/dlang/dub.

Restriction on a specific sites and version control is unexpected 
for open-source project. Is there are any possibility to use 
sourceforge or non-git repositories?
