I would mostly agree, though not entirely. Continuing with the anecdata, at times I had enough waiting and put my prototype into prod, with significant hardening. I can't say I always got it right, but usually 3-5 days of very focused poking made the thing at least reliably run at the desired cadence, with rare but loud and graceful failures. For sure though, there is a tax for doing it all "properly".

Even then though, I have the impression that Python just makes it easier to write it all more quickly. It just doesn't invite you (as much) down rabbit holes of doing things even more properly.
