Okay, I totally get your point.

I still struggle with IPv6 and simple-connect [1]. I have to admit that 
I'm not deep enough into QMI to completely understand what is going on 
behind the scenes but at least with +cgdcont I'm able to connect to my v6 
apn. Therefore sending an AT command seemed a good way to do that. But of 
course that totally fits your explanation "users putting 'quirks' 
themselves where a proper fix would be to fix the plugin in use". This is 
the main purpose for me to use the AT commands at the moment. Possibly 
there will be other special use cases in the future.
