It doesn't seem like it to me. ISTM that they're implying that most sql tools have a gui component which isn't friendly to running remotely over an ssh session.
I've personally never seen a good experience of display forwarding over ssh.
Of course, most people and tools get around this by tunneling a connection to the database over ssh and running the GUI locally.
I believe their next sentence took away the need to try to infer anything, and in fact made their point quite clear:
> A grid with monospace characters is perfectly suitable for that.
Are you implying that people only write code inside of a terminal ssh session?
