That what we will be doing for 1.13, the first few builds will only have the bare bones of what we have gotten done.
But we arnt working on FORGE itself right now, we're finishing up the installer, gradle, building, etc...
All the NON-Forge parts of the modding ecosystem.
Once those are done and good to go, then we'll start forge builds and start working on Features.
As it sits there are only a few things left, the most nosed being IntelliJ run configs and TESTING.
I've been public about this on my twitter, so those who wanna help can help., if they know how.
