In order for media change to work with Linux host CD-ROM it is

Maybe we should fix the bug in Linux (and backport as necessary)?
I think cd-rom assignment is sufficiently obscure that we can require
a fixed kernel instead of providing a workaround.
Do reads fail after CD change? Or do they succeed and the size is just
reported incorrectly?
If it's the later, I'd agree that it needs fixing in the kernel. If
it's the former, I'd say it's clearly a feature.
