Yes, you are completely correct.  TBD41 is 41 and, right, the Recommended column (with value N) stays.

Thanks Rich for the suggestions, will update the draft. Actually there is a typo in the draft, the TBD4 should be in SupportedGroup registry instead of HashAgorithm. So I guess the nunber of TBD4 might be 41 and the Recommended still remians?

Looking at https://tools.ietf.org/html/draft-yang-tls-tls13-sm-suites-00<https://urldefense.proofpoint.com/v2/url?u=https-3A__tools.ietf.org_html_draft-2Dyang-2Dtls-2Dtls13-2Dsm-2Dsuites-2D00&d=DwMGaQ&c=96ZbZZcaMF4w0F4jpN6LZg&r=4LM0GbR0h9Fvx86FtsKI-w&m=BOyJ17MYeXYNjETacf5xP3XcyBXx5ireIgTePS9A40g&s=0PAZs7PUEAldTXT2gjbpM-86LEmZjSBpbHIeb-lGAKA&e=>LEmZjSBpbHIeb-lGAKA&e=>, the IANA considerations in particular, I suggest the following:

Update the TLS Cipher Suites table to include
