A TimeStampSignature is a new type of signature (as defined in PAdES Part 4 or ISO 32000-2), which is why Acrobat shows it as a separate signature with a unique type. It's not the same as a standard signature with an embedded timestamp.
TimeStamp Sigs, as part of PAdES, are valid/legal in the EU so not sure about your "legal non-go".
