There are 3 different use cases:

Indicating ...

• an (update)
  Reason: courtesy, fairness (b/c there is no history feature here)
• a sub thread which is a specialization and not a thread drift like here Re^4: Ternary Quizical behaviour? (Ref vs Alias) ,
  Reason: sensible description in the title
• a complete thread drift kind of Sundial-101 again (was: MongoDB) °
  Reason: Total drift, but new title spares us from considering/messaging the cabals

> sensible argument for doing any of this

Overall reason:

• we keep re-linking valuable nodes and the title appears automatically, Ref vs Alias is a far better title
• we have node overviews, like best nodes etc.
• inheriting (update) makes no sense at all

°) there are less controversial examples, please don't crucify me for mentioning the should not be named
