TBH It is a bit disheartening to see this issue closed when all proposed solutions do not sufficiently solve the issue at hand, I really like svelte but if this is how feature requests are handled I am probably not going to use it in the future.

In fact, developers often tend to forget a simple, almost elementary fact: if users want to close the application or leave a site, they will — doesn’t matter which obstacles are placed on their path to the exit-button. The more obstacles there are the more negative the user experience will be.
