No you don't need the extra dimensions and OpenAI is generally the worst at everything except being the first to market.
Also, ditto your comments on vector database shilling. Vector Databases are just like any other database in that I'll host them myself. I don't need a dedicated VC backed company for a database.
Dimensionality reduction is an extremely destructive operation. Losing even the wrong single vector component of an embedding is massively damaging to down stream performance.
