Not only does Google take a long time to review extension updates, but Chrome pulls extension updates infrequently. So even if you manage to get an update pushed to the store in 24 hours, it may take another day or more before your users actually get the update. All of this put together means you really shouldn't trust Chrome extensions for anything important. If there's a security vulnerability in something like your password manager, the update is going to take days to reach your system.
