Hi,
When I set readonly=on on a dataset then no new files are allowed to be
created.
However writes to already opened files are allowed.
This is rather counter intuitive - if I set a filesystem as read-only I
would expect it not to allow any modifications to it.
I think it shouldn't behave

Both very good points. But I

Suppose you zfs send from a primary server to a backup server. You want
