Despite being on the amd64/23.0/hardened profile, my x86-64-v3 binhost isn't hardened. As of 2025-11-09 this has caused me no issues despite possibly being bad practice.
PAX is deprecated ⇗.
Therefore mixing binhosts will probably be fine.
I also add binpkg-request-signature for key verification (see the wiki ⇗).

There was one network issue I had to work around.
After removing /etc/portage/gnupg and running
my WiFi hung after primary openPGP keys were generated. I discovered that my WiFi was blocking the hkps:// protocol, so I had to use mobile data to run the getuto part.
