Thanks! I should have clarified that I am developing a package that keeps track of the currently active window and executes certain code when the selected window changes (similar to auto-dim-other-buffers, if you are aware of it). I can't control what the user of my package does, in terms of combining `save-window-excursion` with `with-selected-window` or otherwise, so I am looking for a solution that works regardless

I guess my only option is have an idle timer that checks if the current selected window is different compared to the last time a `buffer-list-update-hook` was called.
