I think the idea you've suggested here, setting an extra
bit or property in on the file as a part of the work flow
is a better idea than the one I had in mind.

Which is I believe covered by one or more of the following CRs:

5105713 want new security attributes on files
6417435 DOS attributes and additional timestamps to support for CIFS
4058737 RFE: new attributes for ufs
        Obviously this needs a ZFS equivalent.

Is passing a new flag through open(2) a way to achieve this,
such as O_DISPOSABLE (that is ignored by filesystems that
don't have any way to handle it), or should tools such as
make check to see if they're creating a file on ZFS and set
the extra bit appropriately with another system call?

Or use acl(2) interface or openat(2) interface depending on how these are implemented.
