This is already available through the -show_data option since years
(but note that the binary data is rendered as a data dump).

My point is that we might opt-out the verbose dump if we have a clear
criterion for opting-in/out. For example -show_data is off by default,
and we could mark special side-data fields with some flags to opt them
out by default.

I still don't understand. The CLI exposes what the API does, so if the
API can't do it, the CLI cannot do either.

"Parsed by FFmpeg" sounds like you are proposing to extend the FFmpeg
API to parse some more information (about the SEI subtype?) and make
it available through some more specific SEI side data?
