Toyota doesn't either. They just recommend a flat 10K OCI for most of their products.
I like having an IOLM. It takes the guesswork out of OCIs and thereby allows you to run a conservative interval with many variables considered.
A flat time or mileage interval will not make sense in many use patterns for any vehicle.
