~/.cache has 0700 file permissions. Other users have no access.

If you remove it while Emacs is running you're lost. Don't do that!

When Tramp is loaded, and ~/.cache exists, ~/.cache/emacs will be
(re-)created if it doesn't exist. Otherwise, /tmp will be used (or
whatever value of temporary-file-directory).

See the initialization of tramp-compat-temporary-file-directory in
tramp-compat.el.

Best regards, Michael.
