Yes it will be coming! The reason it's taking a bit longer is because of the automated rebase that happens after you merge part of a stack. There are some legitimate security concerns because of this so multi-fork stacks (a stack which includes multiple different forks) are probably out of the question for now.

We will support a stack that is fully contained within a single fork, where the entire stack targets the original repo.

For example, a contributor who has a fork (user/buzz) of the original repo (org/buzz) could create the following stack:

``` frontend → PR #3 (base: user/buzz:api-endpoints) api-endpoints → PR #2 (base: user/buzz:auth-layer) auth-layer → PR #1 (base: org/buzz:main) org/buzz:main (trunk) ```
