Branch list, the enigma

System

Can anyone give me a 'heads up' on the latest rumours surrounding how the available_templates.cfg branch list now works in 6.7.1. please?
Can one now limit a workflow to a Branch sub-folder for all types of workflow initiations (tt_data, submit etc)?
Does branch now work for worklfows initiated directly from a Workflow job, as hinted at by Ghoti back in 2005?

Much thanks in advance, as always
