I think `recentf-save-file' for example is no different. And
org-id-locations-file. And custom-file, if you happen to save safe
buffer-local variables by answering "!" in Emacs prompt. And many many
other places.

I do not think that file name, even from encrypted volume, is something
we need to worry about.

I even suspect that, for example, browser cache often contains all kinds
of secrets, like files associated with web pages were you logged in. And
they can be read by anyone familiar with the layout! (like
https://www.nirsoft.net/utils/chrome_cache_view.html)

That said, do not worry about this issue being forgotten. But it is not
easy to design cleanly. I am thinking about it.
Of course, if you have good ideas or patches, they are welcome.
