My rationale (didn't check and assume it was I) was that it is
better to fail in a way more likely to alert the incautious user
that they have misused the tool, rather than to silently
accept questionable usage.

Considering it has been this way for 10 years, and has
exposed real bugs in client code, I am inclined to prefer
the existing behavior.

Don't shoot the messenger?
