Where did we land on Invocation spells being Warlock spells?

Quote from Pantagruel666 >>

None of the invocations give spells that are on the Warlock spell list.

Fiendish Vigor gives False Life which is a Warlock spell for Undead Warlocks.

One With Shadows gives Invisibility.

Whispers of the Grave gives Speak with Dead which is a Warlock spell for Undead Warlocks.

(Cheating?) Master of Myriad Forms gives Alter Self which might wind up as a Warlock spell for UA Primordial Warlocks

There are also scenarios involving certain Backgrounds and Feats which may or may not add invocation spells to the Warlock list, but those are extreme edge cases.
