The proper place for core.typed

Hello,
I notice there have been several issues opened due to the same root cause - that core.typed was not being required in the project's dependencies. I stumble on this issue and forget to add it myself at times.
Where do you think is the proper place to resolve this issue?
As far as I understand it, even with the type checks disabled, squiggly is still broken without requiring core.typed?
The possible solutions I see are:
- Add a warning to require it in the README
- Require in a profile (should also be specified in the readme)
- inject the dependency

Thank you for the work you do on this project
Ben
