Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. The counter-case has not been addressed. Somebody upthread described the situation that does not fit, and the thread moved on rather than engaging with it, which is the failure mode this board is supposed to avoid.

That is right for the common case. Whether it is right for the case being asked about depends on a detail that has not been given.

Genuinely useful, thank you. I had the facts and not the framework. Printing the relevant bit and taking it with me.

From the other side of the consultation, briefly. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.

This is my experience too, for whatever a second data point is worth.
