Changing the default behaviour to always include the equivalent of \noBeam
is very easy, just add a line to the definition of \breathe in 
ly/music-functions-init.ly
Making it customizable with a context property setting is slightly more 
advanced
but can still be done in Scheme.

Since this will lead to an incompatible change of the default layout, I 
would
propose to let convert-ly write out a warning about this change, if \breathe
is used in the file.
