So we currently have:

1. "deviation": [
     {
       "module": "foo-devs"
     },
     {
       "module": "bar-devs"
     }
   ]

and the proposal is to have instead

2. "deviation-module": [
     "foo-devs",
     "bar-dev"
   ]

I fail to see why #2 is harder to use for clients, I would say it is the
opposite. Also, #2 doesn't provide less information than RFC 7895 - the
revision parameter is readily available in the "module" list.

I also expect that this data will be used not only in machine-to-machine
communication but could also be perused by humans - see
e.g. draft-lengyel-netmod-yang-instance-data. For this purpose, #2 is a
clear winer.
