I suppose your intention is for the EST client and server to support Content-Formats just like in RFC 9148, i.e.:
"Content-Format 281 MUST be supported by EST-coaps servers. Servers MAY also support Content-Format 287. It is up to the client to support only Content-Format 281, 287 or both."
I think it is good to have an explicit statement here too.
Like RFC 9148 does in its Table 3, it is good to also recap the Content-Format identifiers used for the different parts of the responses from /skg and /skc.
