No I was mistaken.

This was me misremembering that the "sloppy logic analyzer" from
Wolfram Sang was OK to merge without any proper bindings, but the
reason there was that this is for debugging only, but I don't know if
someone told him that or it's his own claim.

This is not for debugging only so it doesn't apply anyway.
