Not sure that's a pro if your use case is just a platform for long running compute intensive jobs. The platform's goals may diverge even more from yours in the future, if a cloud provider's use case is the cause for a big rewrite for example.

A small part of said inertia is perhaps the CADT model of software development in action up close, where functionality can be redeveloped multiple times because someone is not satisfied with the outcome.
