This is one of the strongest points for HIP-3. The XPL market along with hyperps generally were flawed upon release: fragile liquidity, dubious oracle robustness, and an adversarial market all resulted in a failed market.
HIP-3's strongest argument isn't compounding liquidity for deployers or Hyperliquid itself, but risk externalization. The value proposition centers on strategic insulation: Hyperliquid maintains its core orderbook integrity while third parties absorb experimental market failures (and successes!). The analog is morpho blue.
Another post HIP-3 mainnet thesis is that the Hyperliquid team likely stops listing markets entirely after launch
As the shift to Hyperliquid as exchange infra continues, HL team can focus fully on the orderbook infra it builds best as opposed to also having to juggle parameterization and execution of one-off market listings (would have likely been better for a dedicated team to have listed the XPL pre-TGE market)
This shift away from the core team deploying markets also removes a layer of regulatory scrutiny and distributes that compliance question over a wider surface area of distributed parties, allowing for a more compliant HL base to build on
