@andoriyaprashant did you intend to close this?

[andoriyaprashant]

@tim-schilling Sir, I made these changes

but after pre-commit.ci's commit, they were reverted, and the changes are not correct. That's why I closed the PR

[matthiask]

The changes still look correct to me? It doesn't matter if it's Homepage under project.urls or urls.Homepage under project -- the resulting key is still project.urls.Homepage. Or not?

Nice! Could you add a short note to docs/changes.rst also?
