No, it doesn’t. It is important to collect this information even if the feature is turned off, because otherwise you can run into the following issue:

1. Autofocus prevention is disabled.
2. The user has one or more tabs open.
3. The user turns autofocus prevention on, perhaps just to try it out.
4. Suddenly the user cannot focus anything in the opened tabs (until they are reloaded). That’s because `vim.lastLoad` would be undefined, making `if !vim.lastLoad or …` in the the focus event handler always true, effectively blurring _all_ attempts to focus anything.
