Deregistering WordPress stylesheets is one of those things that we don’t always have to consider.
If you’re starting a project from scratch, then it’s usually safe to say that you’re starting a project at ground zero and have control over most of the assets that are to be enqueued in the project.
On the other hand, if you’re coming into a project at a later date or you’re working on a plugin that has to work in conjunction with another plugin that might use a shared stylesheet then you may need to deregister an existing asset to make sure everything works well together.
