HTML Sanitizer Autowiring a Total Mystery

Lines 214 to 215 in c59af97

	service. This service will be :doc:`autowired </service_container/autowiring>`
	for services having an ``HtmlSanitizerInterface $appPostSanitizer`` parameter.

This one sentence seems to go completely without explanation. It links to the Autowiring page, which says nothing about named arguments.

The closest thing I could find is here https://symfony.com/doc/current/service_container.html#binding-arguments-by-name-or-type

That part of the Service Container doc is suggestive of autowiring for specific argument names, but again says nothing about how the service name is being magically converted to a name binding.

Where the heck did this $appPostSanitizer name come from? Is it case sensitive? Can I change it? What happens if I use a different name that's not configured? This just sounds so fragile without some logic behind it.
