So, I am a developer of integration mod between MI and CC:T, and I faced issue with my integration when this package was moved from "megane" to "waila".

Unfortunately, holders are very suitable for information reading integrations and I really need to use this interfaces rather than check all their implementations. Can I suggest for 1.20 version move this holder to separate package inside api for example?

Which holders are you actually using, and which properties of the components are you reading? This is important so I know what to expose in the API. 😉

See #550.

Thanks, it is perfect!
