It seems to me this can only be a viable mode of operation if you're always

Would you run like that, if it offered you the potential of maybe 10x faster
write performance?

Absolutely not! DB reliability is crucial to us. Transaction durability too, esp. since we are using syncrepl in refreshAndPersist mode and numerous production systems (consumers) are affected.

Thanks for asking!
