Hi @johanneswuerbach

1.20 Enhancements Lead here checking in. Do you intend to go beta in 1.20? If so, please note that the Enhancements Freeze is October 6th, by which time your KEP should be:

• implementable
• have test plans
• have graduation criteria.

I left a comment on your KEP with some notes to bring it to the correct dir structure. Let me know if you have any questions.

Best,
Kirsten
