My point is that I don't think someone new to psql (or even
experienced in psql, such as myself) has a hope of reading the
documentation for this option and understanding why they might or
might not want to use it. Even your description here, "removing
issues with variable quoting" is pretty vague. Maybe you need to
provide some examples of the pros and cons of using this option.

Hmm, the :[foo] and :{foo} syntax looks sort of cool. But I don't
understand why it would need any more server calls.
