Today, clearing cookies does cause the user to rebucketed (even though localStorage still has all the info from my previous optimizelyEndUserId value and now the new one too)
1- Over time locaStorage could get full.
2- We are contracted for a certain number of visitors. If cookies get erased, they count as a new visitor
3- In long running tests, only high-value frequent shoppers will actually stay in one variation the entire experiment

I think, this is an issue for the optimizely dev teams to solve the case @JasonDahlin mentioned. If cookies are limited to 7 days, experimentation will not work for us anymore. Our conversion latency is about 35-40 days.
There is no official info from optimizely?
