MARC codes and Bibframe

For those who choose $4 relator codes as opposed to $e relator terms,
and use MARC codest (ignoring differences between the terms associated
with those codes and RDA terms), what happens in Bibframe?

Will Bibframe carry over the MARC codes?  Will we have a whole new
list of codes?  Will that option vanish?

It would be good to know this by April 2013.
