@sun @icedquinn @moth_ball I don't think the delay in removing funds from an optimistic rollup is a big deal that actually affects normal people. in real life, most ethereum users can just use a single rollup. moving money directly off of a rollup is not something that normal people should have to do. if a person needs to migrate funds from one rollup to another this can be done instantly using swaps, and good wallet software should be able to abstract it so the user doesn't need to know it's happening.
