Earlier discussion around unlocking: Automatically remove gauges that are not voted for - Governance Proposals / Gauges - Frax Finance Governance
TLDR;
The ideal setup would be that stakers get the possibility to rebalance their locked stake. This way stakers can react to risk and drive liquidity in line with gauge voting. If too challenging, I’d opt for an automated unlock process based on the gauge voting system. This way there are clear rules for stakers and protocols and we don’t have to go through a heated governance process for each and every unlock.
