What do you propose?

I think we agree. I wouldn't expect a developer on an operational task
to preserve it[1]. But I think that any discard should be explicit.
Tooling can help: by refusing to proceed by default, and requiring the
developer to be explicit about whether to preserve or discard before

I'm partially contradicting myself by making an exception to the
default. If the default is "fail", as I suggest, then batch processing
archeology will become painful. A developer of such a script is unlikely
to know about the edge case until a batch job fails, and the same
principle applies to any other edge cases, of which there is a generally
increasing set. So there should be a "try not to fail" mode which such
an archeologist could enable that sets all relevant defaults


[1] Though perhaps there's some value in preserving it in a low touch
stability scenario, such as an unrelated update to a package in a stable
release. But I don't think that case affects any design decision today.
