Hi! So we're using Koin Embedded in our KMP library here:
github.com/Catrobat/catrobat-ai-tutor
So far it's working smoothly when integrating it into the project. We then tried Custom Relocation to make the package name match our org package name, but we had a bit of difficulty setting up the script, because of some inconsistencies between the koin docs, the koin-embedded repo readme.md, and the shell scripts themselves. We did get it working (with some adjustments in the scripts), but in the end we decided not to go with it.
Since it is still in beta, I think it would be good to report the issue in this channel, to help make it better. You can see the detailed problems here in the PR:
