As with software development, some people have done this before and learned their lesson, others never do.

Once upon a time it was completely normal to have manual processes in your final build process. Something like a word processor in the 1990s would have one of the team sat at a machine building the "gold" binaries by hand, maybe following a checklist, likely hand written. OK, so we need to drag all the files except these two into this folder, then run this program...

Today, hopefully most of you today would see that's awful and you'd forbid it on a project you led and insist on CI instead.

Toy Story in particular had to be re-rendered to produce the 3D re-release over a decade later, and Pixar did that. They chose not to later re-render to 4K because in their opinion it isn't worth the effort compared to just upscaling it.
