SUMMARY In Gedit, it's possible to press control+shift+T to reopen a recently closed tab. It is very frustrating to see this basic option missing in Kate.
That is a valid wish!

I'd like to work on this. I have a prototype that can restore closed documents, but it doesn't work with the configuration window. Would it OK to have only a "Reopen recently closed Document"?
Implemented by Ben Gooding with the commits in https://invent.kde.org/utilities/kate/-/merge_requests/1398 for Kate 24.05! Note that right now the action has no shortcut, you have to do that yourself. This may change in the future.
