Does parameters.yml still work?

I'm not a Symfony guy, so forgive the ignorance.

Does parameters.yml still work to override things in the current versions of Symfony? I couldn't seem to get them to do anything, and instead had to use services_foo.yaml files.

For example, setting a user and password for the /admin, adding it to parameters.yml had no effect, but creating a services_dev.yaml and a service_prod.yaml with the admin.auth and admins.users worked.

BTW, for any other non-Symfony folk, in prod when you change the config / env, you have to:

php bin/console cache:clear
