I think the only place where it matters is when you start a new ML subprocess. There can be only one default, but you're always given the chance to choose a different (non-default) program. It would be easy to define 2 keyboard macros with distinct keybindings so even that minor inconvenience would go away.
One trick I found useful with PolyML:
structure Fs = OS.FileSys structure P = OS.Process structure T = TextIO
fun build_dir d = let val cwd = Fs.getDir () fun print s = T.output (T.stdOut, s) in Fs.chDir d ; app print ["\n", "Entering directory `", cwd, "/", d, "'\n"] ; use "load-all" handle _ => P.exit P.failure ; app print ["\n", "Leaving directory `", cwd, "/", d, "'\n"] ; Fs.chDir cwd end
the "Entering directory" and "Leaving directory" will let next-error know where the faulty file is and stop it from asking stupid questions :-P
