Manufacturers used to recommend short OCIs to keep business in their shops. Then while doing the oil they might see some other service required.
Now the EPA is leaning on them to use longer OCIs to reduce the waste stream and cars that require less service are viewed as cheaper by the buying public.
Toyota is now at 10,000 mile OCI with synthetic oils. I use that until warranty is over then move to 15,000 mile OCIs.
On both my Strom and my Tenere I use an OCI of 5,000 miles with synthetic oil. I have tested oil from both of them and could easily go 7,500 to 10,000 miles. I use shorter intervals because I pamper my bikes. I do not mind wasting a little money on them.
