Unexpected behavior with `docker compose down`

I have a compose file with 3 services:

```yaml
services:
 foo-api:
 bar-api:
 baz-api:
```

If I accidentally type `fooapi` with `docker compose down`, like this:

```shell
docker compose down fooapi
```

Then all services go down.

It must error instead. Or is this an intended behavior? Please enlighten me.
