allow me to clarify. What I meant was "disassemble and reverse engineer" the ECU. They have to figure out what all the tables do, even if it doesn't have some actual lock on it.

Let me preface this by saying that I don't have a crystal ball and I don't know what will happen in the real world when somebody actually tries to crank up the port injectors at full load and high rpm repeatedly. There might be increased wear of the direct injectors in a slow and noticeable fashion. There might be random and catastrophic failures. There may be some negative effect that is difficult to quantify and barely noticeable--negligible in essence.
With all that out of the way, allow me to post the material directly from the source paper on the IS350 2GR-FSE engine:
