Right, of course; I didn't mean to imply that your config file would
make the command line be unavailable, nor did I mean to imply that it
isn't useful (quite on the contrary.)

What I meant was that the presence of config file does not avoid the
user-hostility of options like "-chardev stdio,id=debug -device
isa-debugcon,chardev=debug" ... for a command line user, the situation
is still the same, and when using Qemu for debugging and testing, this
is one case when you would be likely to run into the command line.

As such, I think there is still a place for the simple command line
options like "-hda", "-serial" and my proposed "-debugcon", in addition
to the full-featured connect-anything options and configuration files.
That's all.
