After looking more closely at the source of DBD::Mock, I agree, it should work as you expect. After reading DBI::DBD I am convinced it should work as you expect. However, it does not. The really weird part of course is that it seems to works for other attributes like PrintError, RaiseError, etc. I am trying to figure it out right now, I will keep you updated.

UPDATE
Found this in the trace output: 

$h->{'mysql_insertid'}=10 ignored for invalid driver-specific attribut

So it seems that DBI will skip over driver specific attributes. According to line 1554 of DBI.xs, only those attributes that start with 'private_', 'dbi_' or 'dbd_' are allowed, all others are ignored. However, this seems to contradict what it says in DBI::DBD
The DBI will actually store and fetch driver-specific attributes (with all lowercase names) without warning or error, so there's actually no need to implement driver-specific any code in your FETCH and STORE methods unless you need extra logic/checks, beyond getting or setting the value.
Hmmmm.
