What happened to "Prolog Commons Project"?

Good day,

I was reading through Chapter 6: Modules of the SWI Prolog documentation.

The documentation page for module/3 says:

The third argument is supported for compatibility with the
Prolog Commons project.

The Prolog Commons project seems very dormant. The git repo indicated on the first page is offline or inaccessible. Is it really live?

Some of the authors I recognize from papers
