Problem: Fetching courses by this API endpoint is very slow for people with a lot of enrollments when filtering only on enrollment_role. Unfortunately, the situation only becomes worse with time, as the number of enrollments increases with each semester to a point where the API is too slow for the end user. This is especially problematic for instructors and administrators who happen to use a Canvas instance in a heavy fashion for an extended period of time (e.g. 3+ years).
Solution: Allow filtering to occur on enrollment_term_id, which, of course, corresponds to the enrollment term in which the course resides. This would greatly improve API endpoint speed and is useful for many use cases where only a current term's data needs to be viewed.
