Ouch!

Sounds even better to me.

[ I can imagine external users of auth-source-pass-entries also
  benefitting from the filesystem guard, but I think we can leave it up
  to them to decide if/when/how they need it. ]

CCing some of the recent auth-source-pass (and ERC) contributors in case
they have any comments on the patch below.

[ The original attachment and the rest of the discussion can be found
  here: https://bugs.gnu.org/76323#11 ]

If there are no objections, I think this can be applied soon.

Yasufuku-san, do you have a copyright assignment to the FSF?
I think this contribution is still well within the limits for being
exempt, but for future contributions perhaps you would be interested in
starting the process now, if you haven't already?
