Engagement can always be monetized better in the future.
It would still show in other metrics, however, as you'd have monthly active users (or accounts), which would take a hit. You'd also see a drop in MRR when an account is paused.
Bear in mind I'm assuming a business that wants clear, accurate metrics so the executive team know what actions to take; not simply a business looking to scam investors out of money ;-)
Growth = New Customers Acquisition - Churn. New customers are expensive for many businesses to get, they have marketing, sales, and promotion related expenses. It makes sense to spend money to reduce churn too, because it’s a cheaper way to boost your growth rate.
If you offer deals to reduce churn, you need to focus on if those deals are just delaying inevitable churn or if they are actually winning back customers. Delaying churn is just a game of spending money to make your books look better for a quarter.
IB growth can fuel business growth, especially during times of low new customer acquisition and or high to moderate churn
I know you're being a little facetious but it is actually a benefit. Many companies have implemented subscription pausing to reduce churn. The reason is pretty straightforward good business: it's easier to reactivate customers who lay dormant for 1 or 2 months than it is to let them churn and have to re-sell the product to them from scratch.
