Would you have reached the same conclusion if the problem had been
formulated in terms of true and false rather than 'Lua' and nil?

The nil value is a special case in Lua's tables. Whether it is good
that nil is a special case is very much debatable, but this cannot be
changed without hefty consequences for compatibility. As long as nil
stays a special case, any contrived example that exposes that nil is a
special case is redundant, and any conclusions derived from such
examples are not well founded and probably futile.
