What is minimum possible SOLID?

It’s difficult to give detailed feedback on generalised suggestions so perhaps a way to go about it would be to do a very simplified version of what you have in mind. For example, a description of the intended problem being solved by the pull request and an example of how one sentence would change specifically.

The Editors are largely the ones responsible for the review of pull requests and therefore would be best placed to give feedback.

Open to other ideas around how to lower the barrier to participation, thinking out loud here.
