A lot of these are good points and need to be taken into account. But not every team persists, or even intends to persist. Not every developer is suitable for training others. I've been on Plenty of teams that formed and disbanded in 3 months, we had a goal of building a prototype and turned it over to the customer. Just isn't a great place for new devs. Alternatively, I worked at slow and steady insurance companies that had all the appropriate processes for risk aversion in place and were great places to teach new devs. They let them stretch their wings knowing that they would be protected by good CI and good unit tests and other defensive practices at an organizational level. Not every team needs every sort of skill or skill level. It's a judgment called each team needs to make, and some teams will decide wrong.
