Would something like the following be an adequate workaround? The idea 
is to have code that works with both Emacs 25 and Emacs 24 (and Emacs 23 
etc., for that matter):

     def get_emacs_from_env():
         emacs = ENVB.get(b'CASK_EMACS')
         if emacs:
             return emacs
         emacs = ENVB.get(b'EMACS')
         if emacs != 't':
             return emacs
         return None

Part of the worry here is that programs other than Bash will be 
affected, and that we need to give people some time to adjust to the 
changed behavior of Emacs, by announcing the planned change in Emacs 25 
and then actually making the change in a later Emacs release.
