Blocked by #495

@Pakisan it does not solve your problem, but it cleans up the definition even more after your PR is merged.

Ok. I thought that this MR is for replace my changes

[jonaslagoni]

No not at all ✌️

@Pakisan I also see you have this change in your own PR, so if it is merged before this one with these changes I will just close this PR 🙂

It's just so I do not forget about it 😄
