Even without all the content that exists only in the EU, there is still a lot of content that is present in the movies, and so remains in canon to this day. However, a lot of additional details - technical specifications, for example - that is provided only by the EU, and when the new Disney canon came into force, not all of such details are replaced by a Disney equivalent. Many areas have been "abandoned" and left blank. But people still have lots of questions about these areas even if Disney does not intend to provide an answer. This question demonstrates this.
Another example (Who is the Leader of the Sith?) represents a more general case: Different answers exist in both canon levels. In such cases, do we have a policy on which canon level(s) an answer should contain if the asker does not specify it?
The star-wars-legends tag is supposed to indicate questions belonging to Legends and/or questions which the asker permits to be answered with Legends. It hasn't been followed hard and fast so far. People continue to give answers containing Legends material when the tag isn't there (I'm guilty of this, but only because it appears to be acceptable in other peoples' Q&As), and askers continue to accept such answers anyway even when they are aware of the canonicity. It appears many people are ok with answers containing Legends even though they didn't use the tag, and I don't see any enforcement that the tag is mandatory if answers containing Legends answers are used.
From my observations, there seem to be a few approaches right now:
- Give both canon and Legends answers, organised separately (I do this currently after observing others do it)
- Given canon-only answers if Legends isn't tagged or asked for
- Give an answer based on either canon or Legends, depending on the answerer
In many questions, I see someone commenting to the asker asking if he wants canon or Legends, even though the tag isn't there. If this is going to happen anyway even with the existing-but-poorly-used Legends tag, I think a guideline should be established so that we don't need to manually ask "canon or Legends?" in comments for the rest of posterity.
