I have over a dozen ssh keys (one for each service and duplicates for each yubikey) and other than the 1 time I setup .ssh/config it just works.
I have the setting to only send that specific host’s identity configured or else I DoS myself with this many keys trying to sign into a computer sitting next to me on my desk through ssh.
Like I can’t imagine complaining about adding 5 lines to a config file whenever you set up a new service to ssh onto. And you can effectively copy and paste 90% of those 5 short lines, just needing to edit the hostname and key file locations.
