  • added unit tests or modified existing tests to cover new code paths, ensuring the threshold for code coverage is met.

I worded it that way cause we've already pushed the removal a few times and wording it that way sets the expectation that the soonest it will happen is 37, not that it is 100% going to happen in 37.

If we're committing to 37, we can change it

I see this config para repeated multiple times.
Can we create a single page, capture the contents of the para and have the config block explicitly point to the single page.
That way any changes need to be done only in one place.
