The 8.3 release notes cover resident key support with compatible hardware.. I have older hardware, but I will still be likely to switch to my u2f key being primary as soon as most cloud services support them. Making sure the right library can load with ssh-agent on nixos (and having a gpg applet/key for devices that don't work with opensc) is less convenient for me than just having separate key identities at work and at home.
