Agreed, I had a roll of E100G I decided to develop in 4 or 5 month old Kodak E6 chemicals just to see what effect it would have. The roll was distinctly yellowish and under developed even though I added developer time. I was still able to correct after scanning although they looked pretty rough on a light table.
