Is there any reason not to adopt this policy with the CDI? It's a different configuration: just one filter instead of a main and pre. So I was wondering if there's any downside to a longer interval.

In general with Filters as they plug up they Filter better closer to the end.
Does that damage or shorten the life of something else? I can only say it does not seem to damge anything on other Filtered equipment.
The main issue with letting the Filter go till performance drops is you could end up on the side of the Road and maybe in bad weather changing the Filter.
If the Filter is expensive perhaps another cheaper Flter could ge added to the system.
I also wait till my Car has performance issues or somthing like 5 years has passed.
