Yep, you're correct, everything is frozen in datafiles when they're in read
only mode (you can have read only datafiles on read only media if you want).
Also, no controlfile records (like checkpoint cnt, checkpoint scn) for read
only datafiles are not changed, I've verified this with controlfile dumps
and diff just in case.
As you said, it's logical.
