Support for Site Studio layout canvas field

Problem/Motivation

I need Default content module to be able to create test cases. If I use command "drush dcer node 123 --folder=modules/custom/demo_module/content/" it will export all entities from given node except "layout canvas" entity. Can "layout canvas" entity be exported by default content module?

Steps to reproduce
