You are correct, I see your point now. > Applications that use keys longer than B bytes will first hash the key using H and then use the resultant L byte string as the actual key to HMAC. SHA1 block size is 512 bit (B=64 byte), and so the key shortening is not needed for a key that has only 256 bit length (or even 512 bit), because it is shorter than the Block size of SHA1 (512bit). (according the sentence above RFC2104 ) The stun-bis actual agility plan use SHA1 and SHA-256 algorithms. AFAIU actually no key shortening is needed according RFC2104. I agree that there is a conflict between RFC 7635 Appendix B, and RFC2104.
