BIP118 confusion / SIGHASH_NOINPUT is now SIGHASH_ANYPREVOUT (i think)

Hi,

I have detected some definite confusion among people who are not aware of the most recent updates to the bip118 draft. I don't know if that's common among readers of these lists.

Substantial edits to the bip118 draft were made through May 2019, including changing its official name to SIGHASH_ANYPREVOUT. The internal heading "Revisions" discusses these changes.

The version in bitcoin/bips was not modified since 2018, until it diverged by collecting a minor fix two months ago. It still uses SIGHASH_NOINPUT terminology.

AFAICT, with taproot activating, the preferred method to ease lightning network client state requirements will now definitely be SIGHASH_ANYPREVOUT.

I am not aware of reasons for bip118's updated draft to sit on the sidelines before consideration by a wider audience.

Apologies, I found the discussion going on here:
