Has that actually happened with any variable in the last 20 years? (my
living memory)

I tried to push the git project to do something like
`ARGZERO=${ZSH_ARGZERO-$0}` for their sh testing framework to work on
zsh and it did not fly at all. I wonder if any such consensus has
actually taken place.

I think it's fine to use a ZSH_ prefix until there's consensus.
