The script wiki (which I realize might not be up to date) says only one pushdata is allowed but I don't see that in the code. https://github.com/bitcoin/bitcoin/blob/e8cfe1ee2d01c493b758a67ad14707dca15792ea/src/policy/policy.cpp#L49 Am I missing something or am I correct to assume that multiple pushdatas in op_return would normally be considered standard?
