Nobody forces you to give up -hda. You get the warning at startup for
raw files just so that you're not surprised if your guest gets I/O
errors for writing a qcow2 header into its boot sector, but I don't
think your guest is very likely to do this.

(But if you do use -drive, media=disk is the default, so you don't need
to specify it explicitly.)
