@EliahKagan (There's also a dryer sense in which a
bug or
feature-request question on a child meta isn't truly a cross-post of such a question on
Meta Stack Exchange: even if about something network-wide, when posted on a child meta it's a claim that the
particular site works a certain way and that
that site site should work some other way instead. Although I think this reasoning is correct, by itself it doesn't seem very compelling, which is why I didn't lead with it.)
