We might use them for replacing other ad hoc parsers. We have a bunch, but -chardev's one is perhaps the worst one. Whether aliases could be useful for replacing others is not yet clear. I initially hoped that they could help us clean up QMP some, but further (and sadly much later) thought led me to obstacles. > and I'd rather use > -object/object-add for chardevs if that's at all possible. How far are we from making -object the preferred machine-friendly interface for creating character devices?
