I think it's a bit unfair to pretend that TLS replay would be the same as having a not entirely updated IPNS record. The threat models are very different.

The corresponding attack against IPNS would be if the attacker could make your perspective of the world go backwards, and that is prevented by the sequence number.

Indeed, but TLS doesn't have the problem of replay at all (we hope), so IPNS is by design susceptible to a threat that the traditional internet is not in the case that your connection is untrusted.
