It is a operational problem that needs solving. One way to solve it
would be to remove the Direct Key Agreement algorithms, since at least
Key Agreement with Key Wrapping is at worst a size penalty, instead of
not working at all.

Then one could convert the algorithm into Key Encryption algorithm so
that compact encoding does not need to double-base64url the already
large KEM ciphertext in compact encoding.

- 1088 bytes double encoded -> 1935 bytes.
- 1088+40 bytes encoded -> 1504 bytes.
