Oracle dependence for bao synths

I saw on the docs that bao plans to use the following oracles for the synth implementation,

I came across a podcast by Julien Bouteloup of StakeDao, where he talks about a better design that doesn’t rely on oracles that leads to a lower fee overall… (see around 56 minute mark in the podcast linked below)

Curious to hear if such a non-orcale based design would be beneficial for bao synths in the future.
