4 weeks is still rather a long lock-up period, Whaleshares has a very long staking period and afaik hasn't really helped them much. People should take the long-term view voluntarily rather than forcefully at blockchain level. If the concern is that existing investors would divest, they have had plenty of time to do so already, especially those here since 2016, they have had many full 13 week cycles as opportunity to divest fully.
