Why isn't the token taken as an input with a default?

I am curious why the token 1) is taken as an environment variable instead of an input, and 2) not defaulted to ${{ github.token }}, which seems to be the idiom on most other actions, especially the official ones. If it's just for legacy/compatibility reasons, totally understandable. Just checking if I am missing something here and if there are some semantic differences that I am missing.

Some workflows may require custom secrets different from ${{ github.token }}. For examples, releases created with ${{ github.token }} do not trigger any events, and if you want them to do so, you will need to provide a personal access token.

Sure. But taking that as an input that defaults to ${{ github.token }} would still allow for overriding it, and is how most other actions do it these days.
