More generally, with most PPP options, successful negotiation of the
option allows but does not compel the sender to use the feature.

If you negotiate away the HDLC Address and Control fields, or use PPP
Protocol Field compression, or enable data compression via CCP, you
may still send uncompressed data if you have a need to do so.

The exceptions are fairly rare and straightforward, such as the use of
ECP, where unencrypted packets are very likely to be dropped by the
receiver for security reasons.
