I've setup my CodeQL to only run on commits merged to development, and not on each PR, because it takes too long. This is my setup:

on:
  push:
    branches: [development, main]
  schedule:
    - cron: '0 7 * * 3'

However, I get this warning:

2 issues were detected with this workflow: Please make sure that every branch in on.pull_request is also in on.push so that Code Scanning can compare pull requests against the state of the base branch. Please specify an on.pull_request hook so that Code Scanning is explicitly run against pull requests. This will be required to see results on pull requests from January 31 2021.

If I don't want to see results from pull requests, is this warning still applicable?
