This is why I don't understand the lack of directives.

'use strict'; at the top of a file was ubiquitous for a long time and it worked. It didn't force rolling back incompatibilities, it let you opt into a stricter parsing of JavaScript.

It would have been nice for other wide changes like this to have like a 'strict datetime'; directive which would opt you into using this corrected behavior.

They couldn't and shouldn't do this sort of thing for all changes, but for really major changes to the platform this would be an improvement.

Or they could go all in on internal modules, like how you can import `node:fs` now. They could include corrected versions of globals like

`import Date from 'browser:date';`

has corrected behavior, for example
