We didn't use to install intel-microcode by default because it's non-
free.  Starting with Debian 12, non-free firmware and microcode are
installed on systems where they are useful, but upgrades from older
versions won't change this.

But I'm fairly sure what you've found is a different issue from what
Olivier originally reported.
