They do! And most of them are considered valuable employees because they can produce features the business wants in acceptable timeframes. It's perhaps possible that the business and management side of the house at Stripe might not want to give that up for a while so all of those developers can re-implement every service. Given that historically something like half of all rewrite projects fail, there's some non-trivial level of risk there. Though I understand if some think Stripe can afford it.
