XADES sign has always_add_key_value: bool = True

[msetina]

XMLSigner describes that always_add_key_value should be false for security issues, but in XAdESSigner the default is true.
Is there a reason for that?
The case is that if we provide X509 certificate, the signed document has duplicate information and verifier requests to use ignore_ambiguous_key_info to disable KeyValue check.
