But once they're on a hard drive, they're ISO images, and technically re-writable.
But so are any ROMs, once they are on a harddrive.

(Obligatory car analogy below)
After a car crash, most people still call their old cars "my old car" rather than "my old pile of scrap metal".
Technically it's now a pile of scrap metal, but calling it by the old name helps you remember its purpose and where it came from.
ISO is generic. I'd use it the same way I'd call a floppy, CD, DVD, or USB drive a "disk".
Therefore
ROM = ISO +[Type/Purpose] (More specific; not less specific)
