Handling an identity over multiple devices

[Luke]

Hi there,


I've been using gpg on a basic level for some time now (signing commits, 
mails, using pass[1]) on different computers and phones, and have never 
cared much for tweaking as it seemed unnecessary. Now I've seen here and 
there that it would make more sense for me to use subkeys for devices, 
so that they all refer to the same identity (me). Reading this, it felt 
like the good, logical thing to do. Yet, after checking some existing 
threads of this mailing list through the archive system, it seems that 
if the subkey subject is brought up, the usual response is "just stick 
to gpg defaults and that's it". However, these threads usually involve a 
person that has a single device and looks for better security for this 
one device.

Now in the case of multiple device, not using subkeys would mean 
creating different keypais, and different identities, which doesn't 
sound nice, right?
