I think it is worth considering whether modules could be mandatory unconditionally for everything.

Why would they want to come up with a long-winded > -drive command line when they can just use -hda instead? -blockdev isn't as hard as it appears - we make it harder than it ought to be by not documenting it well and carrying on using -hda/-drive in examples so users have little good guidance. Then when people go beyond the needs that -hda can service, they have an worse experiance as a result. Having many different ways to do the same thing and not getting rid of enough outdated/obsoleted stuff is what has always created confusion for QEMU. Also why it is -hda when it is created a SCSI disk (sda), or a VirtIO disk (xda) or a SSD (mmcblk0), or the guest is calling it C:\ :-) Yes, -hda is simple, but it is also nonsensical historical cruft. All the various "convenience" args are also something that could be provided by a higher level launcher script that translates to the canonical syntax, even if they're not in qemu-system itself.
