Risks of not having strict mode enabled

[lcsmas]

Firstly, thank you for the fantastic work on this project 👏.

Our team is currently engaged in a project where enabling strict mode would demand extensive refactoring, which we unfortunately cannot allocate time for at the moment. We have, however, enabled strictNullCheck.

I came across this discussion: #1755. It mentions the primary issue being incorrect inferred types. Yet, @colinhacks also refers to "other unexpected behaviors", and I'm concerned about introducing a dependency that might destabilize our project.

Could someone provide a detailed perspective on the risks involved? Specifically, I'd like to know if strictNullCheck is sufficient, and if there's a portion of the source code that would shed light on the potential risks.

Thank you in advance.

Best regards,
Lucas
