We can agree that "most" is a speculation?

It might not be fantastic, it is a relatively standard term[1]. While
I'm not a fan of either the Premul or Unpremul, the advantage of the
"un" version is that they form a useful pair.

Nuke is as attached in the JPG.
Houdini offers both "Multiply by alpha" and "Divide by alpha" in their
Premultiply node.
Shake was manual IIRC.

With respect,
