Not really abandoned. It's just not the main priority anymore. And perl6 decided to do something else, to go forward with a very shortsided and wrong approach (again).
There are two major blocks here,
1) the parser surviving a GC. There was one help from outside, but without real code. It almost got fixed by myself recently. macros depend on this, and improving the compiler and adding a matcher on macros.
2) threads support for the GC. hard problem. would need to switch to boehmgc, as fellow Tiny(Ruby,Python) folks did with this codebase. But they got not much farther. Only wren did. I liked his approach.
The TLS cert if unfortunately out of my hands. Someone else is maintaining the domain.
