I am not sure that it is worth it. With \alternative being a frequently 
used construct, this is going to be pretty disruptive…

Maybe it's possible to introduce other syntax, like another spelling for 
\alternative, or just using \volta without an \alternative block (there 
are reasons why this doesn't produce volta brackets right now, but there 
was a back-and-forth in that respect and I don't recall how it ended up 
exactly).
