Sure is; but we do bonding for a reason.

There are other interfaces, like various VPN's and WWAN cards, where 
NM's notion that non-bootup connections belong to users is a useful thing.

The upstream documentation has some info; the man pages (nm-applet(1), 
nm-connection-editor(1), nm-online(1), nm-tool(1), nmcli(1), 
NetworkManager.conf(5), nm-system-settings.conf(5), and 
NetworkManager(8) all have useful information.  I'm sure it could be 
improved, but so far it's been useful to me.  I should probably edit my 
initial sentence to 'NetworkManage is fairly well documented' instead, I 
guess.

Agreed.  They're almost as opaque as SELinux avc denials.
