Re: Oh no
I don't suppose you've looked closely at what curl does because if you had then you'd notice it has a lot in common with FTP. The entire web ecosystem is based on FTP's ad-hoc framing and control protocol to manage data transfers and access errors.
The problem with "clicking on a link and data appearing in a window" is that its making a lot of assumptions about who or what is clicking on a link and what is going to happen to that data. Since web protocols are being promoted for IoT devices -- a dumb move, IMHO -- the data intended for human eyes only will have to be parsed by less than ideal mechanisms such as those used be EXPECT to manage terminal sessions automatically.
