When Apple introduced OS X, it was possible to acquire OSX and to
install it on Macs that already had OS9 installed. It was then
possible to boot either into OS9 or into OS X, at the user's option.
The dual-boot Macs included many G3s and G4s. Apple did not support
OS X on 604e PowerPC machines that had third-party G3 processor
daughter cards installed.
For some time after that, Apple sold Macs that would not boot into
OS9, but could run OS-9-flavored Classic.
Eventually, Apple began selling Macs that could not/would not run
Classic, and an OS that did not support Classic (OS 10.5).
These were design decisions by Apple.
