I see your point, but I think when migrating over a million loc, it's a question of practicality. Incrementally migrating a project from Python 2 to 3, between which at least large-scale architectural patterns are more-or-less identical, is a completely different story from migrating to Golang, which uses drastically different paradigms to structure code and think about data flow.

Reminds me of some of the points made here: https://www.joelonsoftware.com/2000/04/06/things-you-should-....

Are most people migrating over a million loc? And if they are, is it one million loc Python service, or a bunch of small services that could all be rewritten independently? Chances are the worst case scenario is very rare.

Golang really isn't that different from Python. They are both incredibly imperative languages with a one way mentality, and most people who learned CS in college will easily recognize both. The major difference is that Go has much less to learn, and very few patterns to speak of.
