YEs, that was the idea behind IDE. It's upward

controller (WD2001 or something like that). I have an IDE card in this
PC/AT. It's just a few TTL buffers and a PAL as the address deocder. It
uses the mainboard BIOS, there is no extension ROM on that card.
...and ATAPI is sideways-compatible with SCSI. :)
