DEFEATURE: remove old/unused SLList -> List construct/assignment

- should ideally avoid SLList in most cases, since it is allocation
  intensive and most places can easily use DynamicList or
  CircularBuffer instead.

STYLE: use push_uniq instead of deprecated appendUniq method

- mark with a 'normal' deprecation instead of 'strict' deprecation
