-### Why isn't this package split into several packages?
-
-Putting all interfaces in one package eases discoverability and dependency
-management. Instead of dealing with a myriad of small packages and the
-corresponding matrix of versions, you just need to deal with one package and one
-version. Also when using IDE autocompletion or just reading the source code, it
-makes it easier to figure out which contracts are provided.
-
-There are two downsides to this approach: you may have unused files in your
-`vendor/` directory, and in the future, it will be impossible to use two
-different sub-namespaces in different major versions of the package. For the
-"unused files" downside, it has no practical consequences: their file sizes are
-very small, and there is no performance overhead at all since they are never
-loaded. For major versions, this package follows the Symfony BC + deprecation
-policies, with an additional restriction to never remove deprecated interfaces.
