Can you also replace other resolution parsing places with this function?

@dzianis-dashkevich thanks for the review!
My first thought was to create a separate PR, as this wasn't the scope of this PR. But if you agree that this PR should include a refactoring commit, I'm all for it. Let me know what you prefer.
I'll do that a little later today.

This is always a good approach, but I believe it is a pretty small change and will be visually easier to review here.
If you feel differently about it, I am absolutely fine with a separate PR
Thank you!

Consider adding a default empty list in the manifest declaration instead of this if statement.

Thanks, that's better!

@dzianis-dashkevich now I remember why I didn't add it to the manifest declaration, because it meant updating a ton of unit tests. If it's OK for you, I'll make the changes this weekend, as I've done enough unit testing for today. 😅
In the meantime, I think it would be best to remove your validation from this PR so that it doesn't get merged by mistake.

@dzianis-dashkevich I did a force push to include the change and update the commit message. I also added two commits, one updating the test fixtures and the other containing the refactoring. Finally, I rebase main into this branch.

I feel your pain... Thank you so much for your outstanding contribution!
