It is, as already covered.

Not itself, but the RFC authors -do- tend to be subject matter experts 
(which is why they're the right people to write the specs).


You might look to the authors, for instance-
"Martijn van Beurden is Full Professor of 'Computational 
Electromagnetics in complex high-tech systems' in the research group 
Electromagnetics at the TU/e department of Electrical Engineering."


Or to the stated purpose of FLAC-
"The standardization process of the FLAC format into RFC 9639 was driven 
by the specific use case of archival and preservation in mind.[1] The 
National Archives and Records Administration has FLAC listed as a 
preferred format for digital audio.[2]"

So yes, it -is- considered "archival" and -is- well documented & specified.

Later,
