Conversion to snake case should convert only case, not other characters

Let’s have a string

\My\AppBundle\App\Twig\GoogleTagManagerDataLayer

I want to convert it to

my.app_bundle.app.twig.google_tag_manager_data_layer

That seems to be the exact case for string manipulation plugin. But it’s currently not possible. If I call “to snake_case” on it, it creates

my_app_bundle_app_twig_google_tag_manager_data_layer

I would expect the plugin to work on case (i.e. only convert [a-z][A-Z] to \1_\2) and not touch unknown characters. Current behaviour IMO severely limits use cases. What is this behvaiour’s use-case?

My other typical use case would be

Some\PHP\SubNamespace -> some/php/sub-namespace.twig (i.e. replace slashes + to hyphen-case)
