Yes, that's a more general solution, but I think Don thinks that solution is also less safe.
I don't have enough experience on this to be able to tell, but generally the less invisible magic there is, the more clear the programs are. So better to limit the magic the few places where it's very useful (and where people know very well it can be present).
