Looks good, I think.

The security considerations section doesn't have much detail, but this doc
seems to be an extension of existing practice to additional TLVs in a way that
wouldn't change the security considerations at all.

The only security-relevant thing I could think of is around memory bounds and
allocation in implementations. When going from limited-size fields to
unlimited-size data across separate TLVs, I could imagine attacks that try to
cause out of memory conditions on a router, or that try to overflow a
fixed-size buffer. But this doc talks about existing TLVs that already work the
same way, so I'm guessing that hasn't been an issue in practice, or has been
mitigated? Do any of the existing docs talk about this? Or is there a size
limit somewhere else (I'm not very familiar with IS-IS) that makes this a
non-issue?
