Status of cFE Secondary Header standardization?

[irowebbn]

Per CCSDS 133.0-B-2, the CCSDS secondary header fields are mission specific, but are registered with SANA. At the link provided in the reference (https://sanaregistry.org/r/space_packet_protocol_secondary_header_format_document/), I do not see any entries for either the cFE Telemetry or Command packet secondary headers.

Crucially, the endianness of the time field in the telemetry header is only documented as a source code comment. There was a similar ambiguity with the command header, but this was resolved with nasa/cFE#297. Is cFS planning to register the header formats with SANA? If not, will the EDS describing this interface specify endianness?
