No it won't. The implicit-RTE extension doesn't come into play until
after you've failed to find a matching RTE. It cannot break queries
that are valid according to spec --- it only affects queries that should
flag an error according to spec.
My question is about what it means to find a matching RTE and when two
similarly-named RTEs should be rejected as posing a name conflict.
Implicit RTEs are not relevant to the problem.
