To be honest most Linux folks giggle on this one as well, it's been more than 12 years that hotplugging screens is not an issue.
I remember having it with vanilla Ubuntu when I started using Linux in 2008/9.

To be fair, as I've mentioned in another comment, I was not strictly talking about hotplugging alone. Detection of external displays hasn't been the issue, usability in some form or another has.
