I would love to be able to "Keep this build forever" from pipeline DSL syntax. Currently this is not available via currentBuild (or http://javadoc.jenkins.io/plugin/workflow-support/org/jenkinsci/plugins/workflow/support/steps/build/RunWrapper.html respectively).

A workaround is to use currentBuild.rawBuild.keepLog(), but this requires adding two security exceptions, one of them being critical...

Simply exposing keepLog(boolean) via the RunWrapper would solve it imho
