Isn't the lint expected to ignore no_std entry points? The lint description contains:

Why is this bad?

Apart from special setups (which we could detect following attributes like #![no_std]),
recursing into main() seems like an unintuitive anti-pattern we should be able to detect.

Thanks for the review! You are absolutely right. I misread the documentation. I have reverted the change that enabled the lint for no_std crates.

Reminder, once the PR becomes ready for a review, use @rustbot ready.

Can you please shorten the PR description to its core, and this will be ready to merge.
