QEMU could easily use a different convention than the OS that it is
running on because QEMU doesn't use the name to access the OS's file
system.  QEMU has to decide "Do I present an IDE interface to the
simulated CPU, or do I present a SCSI interface?"

My mistake, it's "drive", although you've already discovered that.

Here's a copy of the basic documentation:

I'm sure that the simulated drive for a "disk" appears to the guest
software differently than the simulated drive for a "cdrom".
