There are discussions to lower the ETH collateral requirements. Right now there is no validator cap so that will lead to issues. The goal is to first set a max validator cap with a rotating validator pool. However, there's still higher priority items to complete first like the merge, unlocking withdrawals, and likely also sharding. Given that, it's liking like this change would come 2 years from now unless priorities change (and assuming there's consensus for such a change).
