> lack of real integration is basically the core design of most Copilot products

I would wager a month's wages that this is the doing of some internal Security Review, wherein a bunch of out-of-touchers decided that the customers will want to prefer to be Safe and Secure instead of getting some actual value from integrating copilot into shell workflows.

Meanwhile people are yolo'ing it with various janky DIY wires and duct-tape githobbits that mash together whatever open weights model and user-level access to the system (or worse).
