If you have a scan head on your MFP then users will want to be able to fax documents from that scan head.  There are already a lot of mobile applications being provided that serve as alternatives to the printer's own control panel, so this operation would allow those applications to support faxout as well.

And FWIW, the current wording is based on the intended conformance of the Semantic Model FaxOut spec, which makes the operation required.

I'm happy to clarify the text here.

Jobs in the ‘canceled’ state were canceled by a User using the Cancel-Job, Cancel-Jobs, or Cancel-My-Jobs operations, regardless of whether any or all of the Job has been processed or partially transferred to its destination URI(s). The “destination-statuses” Job Description attribute (section 7.3.1) provides detailed information regarding the progress of the job prior to cancellation."

The latter.
