strict mode

Couldn't find a discussion on the topic.

What's the logic behind not enforcing strict mode in standard?

Knowing that Node ^4.0.0 requires strict mode to be able to use the new ES6 let, const keywords, function-in-blocks and classes.

My guess is so that you can check for snippets of a file, but I don't know enough about the project's history to make an authoritative comment.

standard already warns for strict-mode incompatible syntax. ES6 already has strict mode enabled by default. I think that between the two, enforcing the "strict mode" pragma at the top of every file should be left up to the authors.

Also: enforcing the pragma would break a ton of packages using standard.

Right, what @yoshuawuyts said.

standard already assumes that your code is running in an ES6 environment, so you'll warnings for things that are strict-mode incompatible. But enforcing "use strict" is going too far, since it doesn't meaningfully change the way code runs for the vast majority of standard users.

If you need node support, just add "use strict" to your files.
