Thank you for testing that.

I think this should go into emacs-29, but it's unclear to me what the
(security) implications are. This change is required to fix
CVE-2021-30873, which is rated "high", however it's over a year old at
this point, and given that Apple are requiring us to explicitly set
this in our code rather than forcing it on us, does that mean they
don't consider it that big of a deal?

Eli, Stefan, any thoughts? Does this look bad enough to force a new
Emacs 29 release?
