I don't necessarily think it affects Solana directly in that way. It just means that the market structure is becoming more efficient. However, if you're following recent updates going on with Jito's BAM, this is the direction they're trying to push for: private txns, maker priority, and the ability for CLOBs to quote tighter spreads.
The market structure on Solana is inherently moving towards whatever direction is more efficient. Think prop AMMs are just front running this in the meantime
