Right, and it's a hard requirement for the CLI to be remotely usable.

The "auto" must be a default. This is what the users expect: the CLI just
working. Defaulting to anything else does them a huge disservice (been

Yep. We could not wait for OSC to implement it because the CLI is
borderline unusable without this negotiation in place. I don't recall what
prevented us from updating OSC, but I think there was a reason, probably
