*Proposed option:* Move the max dimension limit lower level to a HNSW specific implementation. Once there, this limit would not bind any other potential vector engine alternative/evolution.
*Motivation:* There seem to be contradictory performance interpretations about the current HNSW implementation. Some consider its performance ok, some not, and it depends on the target data set and use-case. Increasing the max dimension limit where it is currently (in top level FloatVectorValues) would not allow potential alternatives (e.g. for other use-cases) to be based on a lower limit. Bruno
