The "Infrastructure VM" service can be (and probably should be) provided by IBP, but it's only ~2% of the cost on Kusama and less on Polkadot, so it can be considered negligible. This is an important part of the system parachain infrastructure. I would still favor a more open structure for collators, possibly with staking or some other mechanism, just as we have on the relay chains, so that there's competition. But, aye, until we have that structure.

This is a bounty that I believe is necessary to maintain for the well-being and future of the protocol. AYE.

I think there should be a better way for curator incentivizatioin.

As system chain collators, we will abstain from voting on this referendum to avoid any COI. However, we generally align with the continuation of this bounty, as it remains the most practical and effective structure to sustain system parachain collator operations at this stage.
