Solution is correct. I left a couple of comments to tidy up the implementation.

Also, consider renaming the PR. Something like "fix: allow revinclude to return more than 10 resources".
It's often better to think about the end result instead of the specific internals being changed when thinking of a PR name.

this const is specific to inclusion params. Maybe rename to MAX_INCLUSION_PARAM_RESULTS
