We may call it differently, but I think both you and I are referring to this part of [JEP 12](https://openjdk.org/jeps/12) (emphasis mine):

> Eventually, the JEP owner must decide the preview feature's fate. If the decision is to remove the preview feature, then the owner must file an issue in JBS to remove the feature in the next JDK feature release; no new JEP is needed. **On the other hand, if the decision is to finalize, then the owner must file a new JEP, noting refinements informed by developer feedback. The title of this JEP should be the feature's name, omitting the earlier suffix of (Preview) / (Second Preview), and without adding any new suffix such as (Standard) or (Final). This JEP will ultimately reach Targeted status for the next JDK feature release.**

Sorry, Rémi, but no. As long as this feature is in preview, I'd optimise for easier removal (back out) of the feature rather than clean combined code.
