Before converting services CLI config to `get_config_dict()` and reuse already present templating - and probably tests (after T2936 was migrated) - the CLI should be streamlined to match the PPPoE implementation.
The difference is, one side calls it ppp-options, the other calls the CLI node ppp-settings. Both perform the same stuff but under different nodes - which won't work when using `get_config_dict()`.
