The list of unhandled RAW codes is: (ill link each and every one of them to their defined lines on UnrealIRCd source)

• 335 - RPL_WHOISBOT - node-irc implementation
• 378 - RPL_WHOISHOST
• 379 - RPL_WHOISMODES - node-irc implementation
• 396 - RPL_HOSTHIDDEN
• 448 - ERR_FORBIDDENCHANNEL
• 671 - RPL_WHOISSECURE - node-irc implementation

Also there's a list of IRC/2 numerics to see possible conflicting numbers:

Apps used:

• UnrealIRCd-6.0.4.2
• bun 0.7.3 / node.js 20.5.0
• matrix-org-irc 2.1.0

There's no such thing as a "RAW code". It just means node-irc does not implement these numerics.

Check out https://defs.ircdocs.horse/defs/numerics.html if you want an exhaustive list.

To be honest I think the unhandled messages are too noisy, it's not a bug not to handle something. However, we should always seek to increase our library of message handlers if that makes sense :)
