Are there Workflow items based on bobf planned/possible

Hello together,

i only found the sentence that ppf can action an workflow out of BOBF and i am wondering that/if we realy still have to build Old BO for Workflow design?

Am i right, that i need to create an old fashioned BO even i want to have the actions in the bobf?

Is there any reusable object to support defining the Workflow tasks based on bobf?

Thanks for any help,
