Fair enough, but as far as your investors are concerned you're changing the definition of churn. I'm sure if they ask, they'll be provided with "pause" metrics, but such data will never see the light of day in any marketing materials.
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 ;-)
Engagement can always be monetized better in the future.
