Hi Paul.  That issue is from an offline discussion between the A-Ds, the 
TRANS WG Chairs, and the 6962-bis authors.  Ben K answered those 
questions (on 3rd Nov 2018) as follows:


"> Do we even need to mark 6962-bis as Updating RFC8446?

Creating a new TLS extension does not require uptading the core TLS spec.
But the suggested text about "new requirements for [...] TLS
implementations" is not good; better to talk about defining an extension
that is used for [stuff].

 > (Can an Experimental RFC update a Standards Track RFC?)

No."


I addressed this in PR#302 [1] by adding [2] the following text to the 
Abstract:

"It also specifies a new TLS extension that is used to send various CT 
log artifacts."


[1] https://github.com/google/certificate-transparency-rfcs/pull/302

https://github.com/google/certificate-transparency-rfcs/commit/e18322235c409bf7150eb0b86384fbddaecc9660
