Why Rails 7 replaces all single quotes with double quotes in config?

I’m updating a Rails 6.1 app to Rails 7 and I see a lot of madness with config files when I run rails app:update. Most lines have conflicts that should be resolved manually. Basically 90% of conflicts are single quotes replaced with double quotes…

Why?

Wasn’t there a principle in the Rails codebase that simple formatting changes (that don’t add anything substantial) were not allowed?

In the referenced commit:

We’re getting rid of all single quote usage, unless it serves a specific purpose, as per the general style guide.
