Cool

Maybe I'm just seeing things. But I'm missing stuff that should be there
- I think the preference should be named something like
useGutenbergForPrettyPrint (btw Markus renamed #useRBASTForPrettyPrint
to #useRBForPrettyPrint)
- an initialize on the class side, that installs the preference
- an unload on the same class, that removes the preference
- An override in Behavior >> #prettyPrinterClass, implemented so, that
you can switch between old pretty printer, rb pretty printer and
gutenberg.

Do you take responsibility if it  makes my code work? ;)
