Hi @MarcZeller,
Yes - Risk Stewards can implement the 18,000 units now.
The process, if we want to increase the cap beyond 18,000 units, then a Snapshot is required.
After the Snapshot is complete and the community has expressed a directional commit, we can then asses if the Risk Stewards will implement the change.
Hopefully we can avoid the need to submit an AIP. The Snapshot will finish in around 4 days time.
